You can use the Power Query add-in to connect to external data sources and perform advanced data analyses. The following sections provide steps for connecting to your data sources – web pages, text files, databases, online services, and Excel files, tables, and ranges. Click the Power Query check box, then OK. The Power Query ribbon should appear automatically, but if it doesn’t, close and restart Excel.

The following video shows the Query Editor window appearing after editing a query from an Excel workbook. The following video shows one way to display the Query Editor. These automatic actions are equivalent to manually promoting a row and manually changing each column type. For example:. The following video shows the Query Editor window in Excel appearing after editing a query from an Excel workbook. If prompted, in the From Table dialog box, you can click the Range Selection button to select a specific range to use as a data source.

If the range of data has column headers, you can check My table has headers. The range header cells are used to set the column names for the query. Note: If your data range has been defined as a named range, or is in an Excel table, then Power Query will automatically sense the entire range and load it into the Query Editor for you.

Plain data will automatically be converted to a table when it is loaded into the Query Editor. You can use the Query Editor to write formulas for Power Query. You can also use the Query Editor to write formulas for Power Query. Note: While trying to import data from a legacy Excel file or an Access database in certain setups, you may encounter an error that the Microsoft Access Database Engine Microsoft.

Step 1: Create a connection with another workbook. Near the bottom of the Existing Connections dialog box, click Browse for More. In the Select Table dialog box, select a table worksheet , and click OK.

You can rename a table by clicking on the Properties button. You can also add a description. Click Existing Connections , choose the table, and click Open. In the Import Data dialog box, choose where to put the data in your workbook and whether to view the data as a Table , PivotTable , or PivotChart. In the Select Data Source dialog box, browse to the Access database. In the Select Table dialog box, select the tables or queries you want to use, and click OK.

You can click Finish , or click Next to change details for the connection. In the Import Data dialog box, choose where to put the data in your workbook and whether to view the data as a table, PivotTable report, or PivotChart. Click the Properties button to set advanced properties for the connection, such as options for refreshing the connected data.

Optionally, you can add the data to the Data Model so that you can combine your data with other tables or data from other sources, create relationships between tables, and do much more than you can with a basic PivotTable report.

Then, in the Import Text File dialog box, double-click the text file that you want to import, and the Text Import Wizard dialog will open.

Original data type If items in the text file are separated by tabs, colons, semicolons, spaces, or other characters, select Delimited. If all of the items in each column are the same length, select Fixed width.

Start import at row Type or select a row number to specify the first row of the data that you want to import. File origin Select the character set that is used in the text file. In most cases, you can leave this setting at its default. If you know that the text file was created by using a different character set than the character set that you are using on your computer, you should change this setting to match that character set.

For example, if your computer is set to use character set Cyrillic, Windows , but you know that the file was produced by using character set Western European, Windows , you should set File Origin to Preview of file This box displays the text as it will appear when it is separated into columns on the worksheet. Delimiters Select the character that separates values in your text file. If the character is not listed, select the Other check box, and then type the character in the box that contains the cursor.

These options are not available if your data type is Fixed width. Treat consecutive delimiters as one Select this check box if your data contains a delimiter of more than one character between data fields or if your data contains multiple custom delimiters. Text qualifier Select the character that encloses values in your text file. When Excel encounters the text qualifier character, all of the text that follows that character and precedes the next occurrence of that character is imported as one value, even if the text contains a delimiter character.

For example, if the delimiter is a comma , and the text qualifier is a quotation mark ” , “Dallas, Texas” is imported into one cell as Dallas, Texas. If no character or the apostrophe ‘ is specified as the text qualifier, “Dallas, Texas” is imported into two adjacent cells as “Dallas and Texas”.

If the delimiter character occurs between text qualifiers, Excel omits the qualifiers in the imported value. If no delimiter character occurs between text qualifiers, Excel includes the qualifier character in the imported value. Hence, “Dallas Texas” using the quotation mark text qualifier is imported into one cell as “Dallas Texas”.

Data preview Review the text in this box to verify that the text will be separated into columns on the worksheet as you want it. Data preview Set field widths in this section. Click the preview window to set a column break, which is represented by a vertical line. Double-click a column break to remove it, or drag a column break to move it.

Specify the type of decimal and thousands separators that are used in the text file. When the data is imported into Excel, the separators will match those that are specified for your location in Regional and Language Options or Regional Settings Windows Control Panel. Column data format Click the data format of the column that is selected in the Data preview section. If you do not want to import the selected column, click Do not import column skip.

After you select a data format option for the selected column, the column heading under Data preview displays the format. If you select Date , select a date format in the Date box. Choose the data format that closely matches the preview data so that Excel can convert the imported data correctly. To convert a column of all currency number characters to the Excel Currency format, select General.

To convert a column of all number characters to the Excel Text format, select Text. To convert a column of all date characters, each date in the order of year, month, and day, to the Excel Date format, select Date , and then select the date type of YMD in the Date box.

Excel will import the column as General if the conversion could yield unintended results. If the column contains a mix of formats, such as alphabetical and numeric characters, Excel converts the column to General.

If, in a column of dates, each date is in the order of year, month, and date, and you select Date along with a date type of MDY , Excel converts the column to General format. A column that contains date characters must closely match an Excel built-in date or custom date formats.

If Excel does not convert a column to the format that you want, you can convert the data after you import it. Convert numbers stored as text to numbers. Convert dates stored as text to dates. TEXT function. VALUE function. When you have selected the options you want, click Finish to open the Import Data dialog and choose where to place your data.

Set these options to control how the data import process runs, including what data connection properties to use and what file and range to populate with the imported data. The options under Select how you want to view this data in your workbook are only available if you have a Data Model prepared and select the option to add this import to that model see the third item in this list. If you choose Existing Worksheet , click a cell in the sheet to place the first cell of imported data, or click and drag to select a range.

If you have a Data Model in place, click Add this data to the Data Model to include this import in the model. For more information, see Create a Data Model in Excel. Note that selecting this option unlocks the options under Select how you want to view this data in your workbook. Click Properties to set any External Data Range properties you want.

No formatting will be imported, and only link text will be imported from any hyperlinks. Rich text formatting only The web data will be imported as rich text, but only link text will be imported from any hyperlinks. This option only applies if the preceding option is selected.

If this option is selected, delimiters that don’t have any text between them will be considered one delimiter during the import process. If not selected, the data is imported in blocks of contiguous rows so that header rows will be recognized as such. If selected, dates are imported as text.

Optionally, type a description of the file, a friendly name, and common search words in the Description , Friendly Name , and Search Keywords boxes. To ensure that the connection file is always used when the data is updated, click the Always attempt to use this file to refresh this data check box.

This check box ensures that updates to the connection file will always be used by all workbooks that use that connection file. To specify how the external data source of a PivotTable report is accessed if the workbook is saved to Excel Services and is opened by using Excel Services, click Authentication Settings , and then select one of the following options to log on to the data source:.

Windows Authentication Select this option to use the Windows user name and password of the current user. This is the most secure method, but it can affect performance when many users are connected to the server. A site administrator can configure a Windows SharePoint Services site to use a Single Sign On database in which a user name and password can be stored. This method can be the most efficient when many users are connected to the server.

None Select this option to save the user name and password in the connection file. Security Note: Avoid saving logon information when connecting to data sources. Note: The authentication setting is used only by Excel Services, and not by Excel. Under Select how you want to view this data in your workbook , do one of the following:. To place the data in an existing worksheet, select Existing worksheet , and then type the name of the first cell in the range of cells where you want to locate the data.

Alternatively, click Collapse Dialog to temporarily collapse the dialog box, select the beginning cell on the worksheet, and then click Expand Dialog. To place the data in a new worksheet starting at cell A1, click New worksheet. Optionally, you can change the connection properties and also change the connection file by clicking Properties , making your changes in the Connection Properties dialog box, and then clicking OK.

If you are a developer, there are several approaches within Excel that you can take to import data:. You can use Visual Basic for Applications to gain access to an external data source. You can also define a connection string in your code that specifies the connection information. Using a connection string is useful, for example, when you want to avoid requiring system administrators or users to first create a connection file, or to simplify the installation of your application.

Click OK when you’re ready to finish importing your data. The web page opens in the New Web Query dialog box. Set any options you want, then click Import. The taskbar buttons for running applications and Quick Launch have also been updated for Fitt’s law. Locking the taskbar not only prevents it from being accidentally resized or moved but elements such as Quick launch and other DeskBands are also locked from being accidentally moved.

The Taskbar grouping feature combines multiple buttons of the same application into a single button, which when clicked, pops up a menu listing all the grouped windows and their number. Advanced taskbar grouping options can be configured from the registry. A button allows the user to reveal all the icons. The Taskbar, if set to a thicker height also displays the day and date in the notification area.

There are significant changes made to Windows Explorer in Windows XP, both visually and functionally. Microsoft focused especially on making Windows Explorer more discoverable and task-based, as well as adding a number of features to reflect the growing use of a computer as a “digital hub”.

The task pane is displayed on the left side of the window instead of the traditional folder tree view when the navigation pane is turned off. It presents the user with a list of common actions and destinations that are relevant to the current directory or file s selected. For instance, when in a directory containing mostly pictures, a set of “Picture tasks” is shown, offering the options to display these pictures as a slide show, to print them, or to go online to order prints.

Conversely, a folder containing music files would offer options to play those files in a media player, or to go online to purchase music. Every folder also has “File and Folder Tasks”, offering options to create new folders, share a folder on the local network, publish files or folders to a web site using the Web Publishing Wizard , and other common tasks like copying, renaming, moving, and deleting files or folders.

File types that have identified themselves as being printable also have an option listed to print the file. Underneath “File and Folder Tasks” is “Other Places”, which always lists the parent folder of the folder being viewed and includes additional links to other common locations such as “My Computer”, “Control Panel”, and “My Documents” or previously navigated locations.

These change depending on what folder the user was in. Underneath “Other Places” is a “Details” area which gives additional information when a file or folder is selected — typically the file type, file size and date modified, but depending on the file type, author, image dimensions, attributes, or other details. If the file type has a Thumbnail image handler installed, its preview also appears in the “Details” task pane.

For music files, it might show the artist, album title, and the length of the song. The same information is also shown horizontally on the status bar. The “Folders” button on the Windows Explorer toolbar toggles between the traditional navigation pane containing the tree view of folders, and the task pane. Users can also close the navigation pane by clicking the Close button in its right corner as well as turn off the task pane from Folder Options.

The navigation pane has been enhanced in Windows XP to support “simple folder view” which when turned on hides the dotted lines that connect folders and subfolders and makes folders browsable with single click while still keeping double clicking on in the right pane. Single clicking in simple folder view auto expands the folder and clicking another folder automatically expands that folder and collapses the previous one.

Windows XP introduced a large number of metadata properties [7] which are shown as columns in the “Details” view of Explorer, in the new Tiles view in Explorer, on the Summary tab in a file’s properties, in a file’s tooltip and on the Explorer status bar when a single file is selected. Users also gain the ability to sort by any property which is turned on in “Details” view. Developers can write column handler shell extensions to further define their own properties by which files can be sorted.

The column by which items are sorted is highlighted. Sorting files and folders can be in Ascending order or Descending order in all views, not just Details view. To reverse the order, the user simply can perform the sort by the same property again. The sort order has also been made more intuitive compared to the one in Windows For file names containing numbers Windows Explorer now tries to sort based on numerical value rather than just comparing each number digit by digit for every character position in the file name.

The right pane of Windows Explorer has a “Show in Groups” feature which allows Explorer to separate its contents by headings based on any field which is used to sort the items. Items can thus be grouped by any detail which is turned on. Microsoft introduced animated “Search Companions” in an attempt to make searching more engaging and friendly; the default character is a puppy named Rover, with three other characters Merlin the magician, Earl the surfer, and Courtney also available.

These search companions powered by Microsoft Agent technology, bear a great deal of similarity to Microsoft Office ‘s Office Assistants , even incorporating “tricks” and sound effects. If the user wishes, they can also turn off the animated character entirely. The search capability itself is fairly similar to Windows Me and Windows , with some important additions. Search can also be instructed to search only files that are categorically “Documents” or “Pictures, music and video” searching by perceived type ; this feature is noteworthy largely because of how Windows determines what types of files can be classified under these categories.

Using Tweak UI , the search user interface can be restored to the one used by Windows Windows XP improves image preview by offering a Filmstrip view which shows images in a single horizontal row and a large preview of the currently selected image above it. Filmstrip view like any other view can be turned on per folder.

This view will be available if the new “Common Tasks” folder view is selected, not with “Windows Classic” folder view. Aside from the Filmstrip view mode, there is a ‘Thumbnails’ view, which displays thumbnail -sized images in the folder and also displays images a subfolder may be containing 4 by default overlaid on a large folder icon.

A folder’s thumbnail view can be customized from the Customize tab accessible from its Properties, where users can also change the folder’s icon and specify a template type pictures, music, videos, documents for that folder and optionally all its subfolders. The size and quality of thumbnails in “Thumbnails” view can be adjusted using Tweak UI or the registry.

Windows XP optionally caches the thumbnails in a ” Thumbs. Thumbnails can be forced to regenerate by right-clicking the image in Thumbnail or Filmstrip views and selecting “Refresh thumbnail”. AutoPlay examines newly discovered removable media and devices and, based on content such as pictures, music or video files, launches an appropriate application to play or display the content.

AutoPlay can be enhanced by AutoPlay-compatible software and hardware. It can be configured by the user to associate favourite applications with AutoPlay events and actions. These actions are called AutoPlay Handlers and there are sets of Handlers associated with various types of content. New AutoPlay handlers can get added to the system when additional software is installed.

AutoPlay settings can be configured per-device in Windows XP from the device’s properties. When a user inserts an optical disc into a drive or attaches a USB camera, Windows detects the arrival and starts a process of examining the device or searching the medium.

It is looking for properties of the device or content on the medium so that AutoPlay can present a set of meaningful options to the user. When the user makes a particular choice, they also have the option to make that selection automatic the next time Windows sees that content or device. It supersedes part of the functions of Imaging for Windows in previous versions of Windows. The Windows Picture and Fax Viewer is integrated with Windows Explorer for functions like slideshow, email, printing etc.

It supports full file management from within the viewer itself, that is, right clicking the image shows the same context menu as the one shown when an image is right clicked in Windows Explorer. Images can be set as the desktop wallpaper from the context menu. It supports successive viewing of all images in current folder and looping through images, [17] that is, after viewing the last image in a directory, it again shows the first image and vice versa. By default, images smaller than the user’s display resolution are shown at their actual size.

If an image is larger than the display resolution, it is scaled to fit the screen Best Fit. When this is done, scroll bars allow for viewing of all areas of the image. The wizard shows a preview of what the printed page will look like with the currently specified options.

Using Tweak UI , the time between images during a slideshow can be adjusted. GIF files are shown with full animation, even when zoomed. Areas of the image can be selected and concealed.

Windows Picture and Fax Viewer saves and remembers its window position and size and supports keyboard shortcuts for all of its operations. Raw image formats , which are the preferred formats in professional photography are not supported, however, Microsoft released a later update called RAW Image Thumbnailer and Viewer for Windows XP for viewing certain raw image files.

The Text Services Framework is designed to offer advanced language and word processing features to applications. It supports features such as multilingual support, keyboard drivers, handwriting recognition , speech recognition , as well as spell checking and other text and natural language processing functions.

It is also downloadable for older Windows operating systems. The language bar enables text services to add UI elements to the toolbar and enables these elements when an application has focus. From the Language Bar, users can select the input language, and control keyboard input, handwriting recognition and speech recognition. The language bar also provides a direct means to switch between installed languages, even when a non-TSF-enabled application has focus.

Although an upgrade of the Windows kernel, there are major scalability, stability and performance improvements, albeit transparent to the end user. Windows XP includes simultaneous multithreading hyperthreading support.

Simultaneous multithreading is a processor’s ability to process more than one data thread at a time. Windows XP supports a larger system virtual address space —— 1. The Windows XP Memory Manager is redesigned to consume less paged pool, allowing for more caching and greater availability of paged pool for any component that needs it.

The total size of memory-mapped files in Windows was limited because the memory manager allocated the Prototype Page Table entries PPTEs for the entire file, even if an application created mapped views to only parts of the file.

A benefit of this, for example, is in case of making backups of large files on low memory systems. The paged pool limit of MB has been lifted from the Memory Manager in Windows XP, with unmapped views dynamically reusable by the memory manager depending on pool usage. Memory pages in working sets are trimmed more efficiently for multiprocessor systems depending on how recently they were accessed.

The dispatcher lock contention has been reduced and the Page Frame Number PFN lock has been optimized for increased parallelism and granularity. Windows XP uses push locks on the event synchronization object if there is no contention as they support shared and exclusive acquisition. Push locks protect handle table entries in the Executive , and in the Object Manager to protect data structures and security descriptors and Memory Manager to protect AWE -related locks.

The kernel page write protection limit in Windows XP is enabled on systems up to MB of RAM beyond which large pages are enabled for increased address translation performance.

Windows XP introduces the CreateMemoryResourceNotification function which can notify user mode processes of high or low memory availability so applications can allocate more memory or free up memory as necessary. In Windows XP, the registry is reimplemented outside of the paged pool; the registry hives are memory mapped by the Cache Manager into the system cache, eliminating the registry size limit.

The registry size is now limited only by the available disk space. The System hive still has a maximum size, but it has been raised from 12 MB to MB, eliminating the issue previous Windows versions faced [37] of being unable to boot because of a large or fragmented System hive. The Configuration Manager has been updated to minimize the registry’s memory footprint and lock contention , reduce fragmentation and thus page faults when accessing the registry, and improved algorithms to speed up registry query processing.

An in-memory security cache eliminates redundant security descriptors. Windows XP supports cross user session debugging, attaching the debugger to a non-crashing user-mode program, dumping the process memory space using the dump command, and then detaching the debugger without terminating it. Debugging can be done over a FireWire port and on a local system. The debug heap can be disabled and the standard heap be used when debugging.

Heap leak detection can be enabled when processes exit and a debugger extension can be used to investigate leaks. Also introduced is a new heap performance-monitoring counter. Windows XP introduces a new low fragmentation heap policy disabled by default which allocates memory in distinct sizes for blocks less than 16KB to reduce heap fragmentation. In low memory conditions, “must succeed” calls are denied, causing a slowdown but preventing a bug check. NTFS 3. There are new APIs to preserve original short file names, to retrieve a list of mount points drive letters and mounted folder paths for the specified volume, and to enable applications to create very large files quickly by setting the valid data length on files without force-writing data with zeroes up to the VDL SetFileValidData function.

For instance, this function can be used to quickly create a fixed size virtual machine hard disk. Upon system boot or the launch of an application, any data and code in the trace that is not already in memory is prefetched from the disk. The previous prefetching results determine which scenario benefited more and what should be prefetched at the next boot or launch.

The prefetcher also uses the same algorithms to reduce application startup times. To reduce disk seeking even further, the Disk Defragmenter is called in at idle time to optimize the layout of these specific files and metadata in a contiguous area. Boot and resume operations can be traced and analyzed using Bootvis. Windows XP includes a Fast Logon Optimization feature that performs logon asynchronously without waiting for the network to be fully initialized if roaming user profiles are not set up.

Group Policy is applied in the background, and startup or logon scripts execute asynchronously by default.

Windows XP reconciles local and roaming user profiles using a copy of the contents of the registry. The user is no longer made to wait as in Windows until the profile is unloaded. Windows XP saves locked registry hives with open keys after 60 seconds so that roaming profile changes can be saved back to the server.

The problem left is that the computer cannot recover the memory the profile uses until it can be unloaded. To make sure the user profiles are completely reconciled correctly during logoff, Microsoft has released the User Profile Hive Cleanup service for Windows XP, which they later included in Windows Vista. Windows XP offers enhancements for usability, resilience against corruption and performance of roaming user profiles. To accommodate the scenario where an older profile would overwrite a newer server profile due to Windows XP’s Fast Logon feature, Windows XP ensures in such a situation that the user registry hive is copied from the server to the local profile.

Deletion of profiles marked for deletion at the next logoff does not fail for locked profiles. For workgroup computers, Windows XP no longer deletes the profiles of users belonging to the Guests group. Windows XP includes some changes to the behavior of Offline Files. Shared folders from DFS namespaces can be made available offline.

Beginning with Windows XP, folders redirected to the network are automatically made available offline using Offline Files , although this can optionally be disabled through Group Policy.

For older Windows NT 4. In Windows XP, System Restore is configurable per volume and the data stores are also stored per volume.

A Disk Cleanup handler allows deleting all but the most recent Restore Point. System Restore supports Group Policy. Automated System Recovery is a feature that provides the ability to save and restore Windows and installed applications, the system state , and critical boot and system files from a special backup instead of a plain reinstall.

A common issue in previous versions of Windows was that users frequently suffered from DLL hell , where more than one version of the same dynamically linked library DLL was installed on the computer. As software relies on DLLs, using the wrong version could result in non-functional applications, or worse. These operating systems allowed loading a private version of the DLL if it was placed in the application’s folder by the developer, instead of the system directory and must be registered properly with the system.

The technology keeps multiple digitally signed versions of a shared DLL in a centralized WinSxS folder and runs them on demand to the appropriate application keeping applications isolated from each other and not using common dependencies.

Manifests and the assembly version number are used by the OS loader to determine the correct binding of assembly versions to applications instead of globally registering these components. Instead, the metadata and CLSIDs of the classes implemented in the component are declared in an assembly manifest described using XML , stored either as a resource in the executable or as a separate file installed with the component.

During application loading, the Windows loader searches for the manifest. Only if the lookup fails is the registry scanned. Windows Error Reporting collects and offers to send post-error debug information a memory dump using the internet to the developer of an application that crashes or stops responding on a user’s desktop. No data is sent without the user’s consent. When a dump or other error signature information reaches the Microsoft server, it is analyzed and a solution is sent back to the user if one is available.

Windows Error Reporting runs as a Windows service and can optionally be entirely disabled. Software and hardware manufacturers may access their error reports using Microsoft’s Winqual program.

This allows distributing solutions as well as collecting extra information from customers such as reproducing the steps they took before the crash and providing them with support links. On old versions of Windows, when users upgrade a device driver, there is a chance the new driver is less stable, efficient or functional than the original. Reinstalling the old driver can be a major hassle and to avoid this quandary, Windows XP keeps a copy of an old driver when a new version is installed.

If the new driver has problems, the user can return to the previous version. This feature does not work with printer drivers. As Windows XP merged the consumer and enterprise versions of Windows, it needed to support applications developed for the popular and consumer-oriented Windows 9x platform on the Windows NT kernel.

Microsoft addressed this by improving compatibility with application-specific tweaks and shims and by providing tools such as the Application Compatibility Toolkit AppCompat or ACT [58] to allow users to apply and automate these tweaks and shims on their own applications. Windows Movie Maker 2 introduced numerous new transitions, effects, titles and credits, a task pane, resizable preview window with dimensions, improved capture and export options, an AutoMovie feature, saving the final video back to tape and custom WMV export profiles.

Windows XP includes advances in Broadcast Driver Architecture for receiving and capturing analog and digital TV broadcasts complete with signal demodulation, tuning, software de-multiplexing, electronic program guide store, IP data broadcasting etc. VMR-7 can mix multiple streams and graphics with alpha blending, allowing applications to draw text such as closed captions and graphics such as channel logos or UI buttons over the video without flickering, and support compositing to implement custom effects and transitions.

VMR-7 features a “windowless mode” for applications to easily host video playback within any window and a “renderless playback mode” for applications to access the composited image before it is rendered. DirectShow 8 includes AVStream , a multimedia class driver for video-only and audio-video kernel streaming. The Scanner and Camera Wizard based on Windows Image Acquisition and other common dialogs for WIA devices have been improved in Windows XP to show the media information and metadata, rotate images as necessary, categorize them into subfolders, capture images and video in case of a still or video camera, crop and scan images to a single or multi-page TIFF in case of a scanner.

The Picture Transfer Protocol PTP implementation has been updated to support all mandatory and optional commands in the PTP standard, and object tree support which allows secondary files associated with a parent file to be grouped and transferred concurrently.

Windows XP includes technology from Roxio which allows users to directly burn files to a compact disc through Windows Explorer. Previously, end users had to install CD burning software. Windows XP’s CD burning support does not do disk-to-disk copying or disk images , although the API can be used programmatically to do these tasks. Audio CDs are burnt using track-at-once mode.

WSF has been introduced besides. VBS and. JS which can store in an XML node in the same file, extra information besides script code, such as digital signature blocks, runtime directives or instructions to import external code.

The WshShell object now supports a ‘CurrentDirectory’ read-write method. Scripts can now be digitally signed as well as verified programmatically using the Scripting. Signer object in a script itself, provided a valid certificate is present on the system. WSH can thus decide whether or not to execute the script after verification.

The signature block is stored in a commented section in the script file for backward compatibility with older WSH versions. By using Software Restriction Policies supported in Windows XP and later, a system may also be configured to execute only those scripts which have been digitally signed, thus preventing the execution of untrusted scripts. Local scripts can also run on a remote machine with the new WScript. The remote script can be monitored by using the Status property.

WSH 5. In earlier versions of Windows Script, to use arguments, one had to access the WshArguments collection object which could not be created externally and required that the person running the script know the order of the arguments, and their syntax and values.

Named arguments are grouped in the Named collection object and have the usual methods like Item, Count, Length as well as an Exists method. Password COM automation object, implemented in the scriptpw. It is built on Terminal Services technology RDP , and is similar to “Remote Assistance”, but allows remote users to access local resources such as printers.

There are several resources that users can redirect from the remote server machine to the local client, depending upon the capabilities of the client software used. For instance, “File System Redirection” allows users to use their local files on a remote desktop within the terminal session, while “Printer Redirection” allows users to use their local printer within the terminal session as they would with a locally or network shared printer.

The clipboard can also be shared between the remote computer and the local computer. Remote Assistance allows sending invitations to the support person by email, Windows Messenger or saving the invitation as a file. The computer can be controlled by both, the support person connecting remotely as well as the one sending the invitation.

Chat, audio-video conversations and file transfer are available. Windows XP introduces Fast User Switching [96] and a more end user friendly Welcome Screen with a user account picture which replaces the Classic logon prompt.

Fast user switching allows another user to log in and use the system without having to log out the previous user and quit his or her applications. Previously on both Windows Me and Windows only one user at a time could be logged in except through Terminal Services , which was a serious drawback to multi-user activity.

Fast User Switching, like Terminal Services, requires more system resources than having only a single user logged in at a time and although more than one user can be logged in, only one user can be actively using their account at a time.

This feature is not available when the Welcome Screen is turned off, such as when joined to a Windows Server Domain or with Novell Client installed. Windows Installer 2. Windows Disk Defragmenter was updated to alleviate several restrictions.

The defragmenter supports NTFS volumes with cluster sizes larger than 4 kilobytes. A command-line tool, defrag. Users who are members of the Power Users group can schedule defragmentation. It has been updated to display process names longer than 15 characters in length on the Processes tab, which used to be truncated in Windows The Delete key can also be used to terminate processes on the Processes tab.

A new Networking tab shows statistics relating to each of the network adapters present in the computer. By default the adapter name, percentage of network utilization, link speed and state of the network adapter are shown, along with a chart of recent activity.

More options can be shown by choosing Select columns The Users tab shows all users that currently have a session on the computer. On server computers there may be several users connected to the computer using Terminal Services. There may also be multiple users logged onto the computer at one time using Fast User Switching. Users can be disconnected or logged off from this tab. Holding down Ctrl while clicking New Task opens a command prompt. User -type certificates can be auto-enrolled and renewed.

Root CA certificates now also auto-update via Microsoft Update. Windows XP can enroll version 2 certificate templates which have many configurable attributes. There are also numerous improvements to certificate status checking, chain building and revocation checking, path validation and discovery. Windows XP includes several Encrypting File System improvements [] The most notable improvement is that multiple user accounts can share access to encrypted files on a file-by-file basis.

A Details button in the Advanced file attributes dialog in the file’s properties allows adding or removing additional users who can access the EFS-encrypted file, and viewing the certificate thumbprint and the Data Recovery Agent account. EFS certificates are autoenrolled in the CA and there is support for revocation checking on certificates used when sharing encrypted files.

Unlike Windows , there is no default local Data Recovery Agent and no requirement to have one, although a self-signed certificate for the recovery agent can be generated using cipher. Windows XP can also encrypt files on a remote server with NTFS if the server is trusted for delegation in Active Directory and the user’s certificate and private key are loaded in the local profile on the server. If a roaming user profile is used, it will be copied locally.

The command line utilities cipher , copy and xcopy have been updated in Windows XP. For faster cache validation, the time for how long the user session key and certificate chain are cached can be adjusted. This disk can be used to reset the password using the Password Reset Wizard from the logon screen. The user’s RSA private key is backed up using an offline public key whose matching private key is stored in one of two places: the password reset disk if the computer is not a member of a domain or in Active Directory if it is a member of a domain.

An attacker who can authenticate to Windows XP as LocalSystem still does not have access to a decryption key stored on the PC’s hard drive. If the user changes the password back to the original password, EFS encrypted files can be recovered. Windows XP prompts for credentials upon authentication errors and allows saving those that use Integrated Windows Authentication to a secure roaming keyring store protected by the Data Protection API.

Saved credentials can be managed from the Stored User Names and Passwords item in the User accounts control panel.

For workgroup computers, Windows XP no longer deletes the profiles of users belonging to the Guests group. Windows XP includes some changes to the behavior of Offline Files.

Shared folders from DFS namespaces can be made available offline. Beginning with Windows XP, folders redirected to the network are automatically made available offline using Offline Files , although this can optionally be disabled through Group Policy.

If a certificate authority is present, then users can a select an X. When that same resource is accessed again, the saved credentials will be used. Windows XP introduces Software Restriction Policies and the Safer API [] [] By use of Software Restriction Policies, a system may be configured to execute or install only those applications and scripts which have been digitally signed or have a certain trust level, thus preventing the execution of untrusted programs and scripts.

Administrators can define a default rule using the Local Security Policy snap-in, and exceptions to that rule. The types of rules include: Hash Rule , Path Rule , Certificate Rule and Zone Rule which identify a file by its hash, path, software publisher’s certificate or Internet Explorer-zone respectively.

For example, an ActiveX control can be restricted to run only for a particular domain by specifying a certificate rule-based software restriction policy. Windows wireless support did not support seamless roaming and auto-configuration. Windows XP’s Wireless Zero Configuration service supports automatic wireless network configuration with re-authentication when necessary thus providing seamless roaming capability and setting the preferred order of connections.

In the absence of a wireless access point, Windows XP can set up an ad hoc wireless network. It has a Quality of Service Packet Scheduler component. Internet Connection Sharing also includes a local DNS resolver in Windows XP to provide name resolution for all network clients on the home network, including non-Windows-based network devices. When multiple applications are accessing the internet simultaneously without any QoS and the connection isn’t fast enough, the TCP receive window size is set to the full window of data in transit that the first application uses in the connection until a steady state is reached.

Subsequent connections made by other applications will take much longer to reach an optimal window size and the transmission rate of the second or third application will always be lower than that of the application that established the connection first. On such slow links, the QoS component in Windows XP automatically enables a Deficit round robin scheduling scheme, which creates a separate queue for each application and services these queues in a round-robin fashion.

IPv6 has to be installed and configured from the command line using the netsh interface ipv6 context as there is no GUI support.

After the network interface’s link-local address is assigned, stateless autoconfiguration for local and global addresses can be performed by Windows XP.

Static IPv6 addresses can be assigned if there is no IPv6 router on the local link. Transition mechanisms such as manually configured tunnels and 6to4 can be set up. Privacy extensions are enabled and used by default. Teredo also helps traverse cone and restricted NATs. Teredo host-specific relay is enabled when a global IPv6 address has been assigned, otherwise Teredo client functionality is enabled.

An open source DHCPv6 implementation called Dibbler is available, [] although stateless autoconfiguration largely makes it unnecessary. Windows XP includes the Background Intelligent Transfer Service, a Windows service that facilitates prioritized, throttled, and asynchronous transfer of files between machines using idle network bandwidth.

BITS constantly monitors network traffic for any increase or decrease in network traffic and throttles its own transfers to ensure that other foreground applications such as a web browser get the bandwidth they need. BITS also supports resuming transfers in case of disruptions. BITS version 1. From version 1. Windows XP components such as Windows Update use BITS to download updates so only idle bandwidth is used to download updates and downloading can be resumed in case network connectivity is interrupted.

BITS uses a queue to manage file transfers and downloads files on behalf of requesting applications asynchronously, i. The transfer will continue in the background as long as the network connection is there and the job owner is logged in. If a network application begins to consume more bandwidth, BITS decreases its transfer rate to preserve the user’s interactive experience, except for Foreground priority downloads.

Windows XP has a Fax Console to manage incoming, outgoing and archived faxes and settings. The Fax Monitor only appears in the notification area when a fax transmission or reception is in progress.

If manual reception of faxes is enabled, it appears upon an incoming fax call. It operates over IPv6. PNRP : This provides dynamic name publication and resolution of names to endpoints. PNRP is a distributed name resolution protocol allowing Internet hosts to publish “peer names” and corresponding IPv6 addresses and optionally other information.

Other hosts can then resolve the peer name, retrieve the corresponding addresses and other information, and establish peer-to-peer connections. With PNRP, peer names are composed of an “authority” and a “qualifier”. The authority is identified by a secure hash of an associated public key , or by a place-holder the number zero if the peer name is “unsecured”.

The qualifier is a string , allowing an authority to have different peer names for different services. If a peer name is secure, the PNRP name records are signed by the publishing authority, and can be verified using its public key.

Unsecured peer names can be published by anybody, without possible verification. Multiple entities can publish the same peer name. For example, if a peer name is associated with a group, any group member can publish addresses for the peer name. Peer names are published and resolved within a specified scope. The scope can be a local link, a site e.

Each peer in the overlay network corresponds to a node in the graph. Nodes are resolved to addresses using PNRP. All the nodes in a graph share book-keeping information responsible for the functioning of the network as a whole. For example, in a distributed resource management network, which node has what resource needs to be shared.

Such information is shared as Records , which are flooded to all the peers in a graph. Each peer stores the Record to a local database. A Record consists of a header and a body.

The body contains data specific to the application that is using the API; the header contains metadata to describe the data in the body as name-value pairs serialized using XML , in addition to author and version information. It can also contain an index of the body data, for fast searching.

A node can connect to other nodes directly as well, for communication that need not be shared with the entire Graph. A Group can be shared by multiple applications, unlike a Graph. All Records exchanged are digitally signed. Peers must be invited into a Group. The invitation contains the GMC that enables it to join the group.

Windows XP introduces a more simplified form of sharing files with local users in a multi-user environment and over the network called Simple File Sharing. By checking the Make this folder private option in its Properties, local Administrators are also denied permissions to the My Documents folder.

Simple File Sharing disables granular local and network sharing permissions. It shares the item with the Everyone group on the network with read only or write access, without asking for a password but forcing Guest user permissions. This newer client works as a system service at the network-redirector level immediately above the file-system , allowing WebDAV shares to be assigned to a drive letter and used by any software, even through firewalls and NATs.

Applications can open remote files on HTTP servers, edit the file, and save the changes back to the file if the server allows. The WebDAV mini-redirector is known to have some limitations in authentication support. Although Windows XP did not ship with the following major Windows features out-of-the-box, these new features can be added to Windows XP by downloading these components which were incorporated in later versions of Windows.

Beginning with Windows XP SP2, the audio volume taper is stored in the registry for on-screen keyboard and remote control applications and can be customized by third parties, [] and Internet Explorer has improved Group Policy settings support beyond security settings. There is IEEE For mass storage devices, Windows XP introduces hardware descriptors to distinguish between various storage types so that the operating system can set an appropriate default write caching policy.

Device Manager provides a configuration setting whether to optimize devices for quick removal or for performance. As mentioned in the above section , Windows XP includes improved support for FireWire cameras and audio video devices.

Direct memory access over the bus from the host to the target allows kernel debugging over FireWire. It is intended to prevent an application or service from executing code from a non-executable memory region. This helps prevent certain exploits that store code via a buffer overflow , for example. Software-enforced DEP does not protect from execution of code in data pages, but instead from another type of attack SEH overwrite.

If DEP is enabled for all applications , users gain additional resistance against zero-day exploits. Therefore, DEP is not enforced for all applications by default in bit versions of Windows and is only turned on for critical system components.

Windows XP Service Pack 3 introduces additional NX APIs [] that allow software developers to enable NX hardware protection for their code, independent of system-wide compatibility enforcement settings. Developers can mark their applications as NX-compliant when built, which allows protection to be enforced when that application is installed and runs.

This enables a higher percentage of NX-protected code in the software ecosystem on bit platforms, where the default system compatibility policy for NX is configured to protect only operating system components. Like Internet Connection Sharing, the firewall has a location-aware policy, meaning it can be disabled in a corporate domain but enabled for a private home network.

It has an option to disallow all exceptions which may be useful when connecting to a public network. The firewall can also be used as the edge firewall for ICS clients. When the firewall blocks a program, it displays a notification. It supports port mapping and ICMP.

Security log capabilities are included, which can record IP addresses and other data relating to connections originating from the home or office network or the Internet. It can record both dropped packets and successful connections. This can be used, for instance, to track every time a computer on the network connects to a website. Windows Firewall also supports configuration through Group Policy. Windows Security Center provides users with the ability to view the status of computer security settings and services.

Windows Security Center also continually monitors these security settings, and informs the user via a pop-up notification balloon if there is a problem.

The Windows Security Center consists of three major components: A control panel , a Windows Service , and an application programming interface that is provided by Windows Management Instrumentation.

The control panel divides the monitored security settings into categories, the headings of which are displayed with color-coded backgrounds. The current state of these settings is determined by the Windows service which starts automatically when the computer starts, and takes responsibility for continually monitoring the system for changes.

The settings are made available to the system through a WMI provider. Anti-malware and firewall software vendors can register with the Security Center through the WMI provider.

Windows Update settings and status are also monitored and reported. From Wikipedia, the free encyclopedia. This article relies too much on references to primary sources. Please improve this by adding secondary or tertiary sources. New features added in Windows XP. Main article: ClearType.

This procedure replaces your current practice of opening the email attachment directly in the email with saving the attachment to the hard drive and then working on it from there. The fact that it originally came from the internet in an email is entirely irrelevant [neither Windows nor Excel know about that at all].

Those Temporary internet files folders are not involved. So, is that helpful or is that what you have already been doing [and hence I have not understood you]? I think I have found the instructions you were trying to follow – the instructions that told you that there was a temporary folder in use by Outlook for its attachments. The instructions are by Roady , a user who is also active in the Office, Outlook section of this forum.

You can then use this shortcut to go straight to the folder to clear it out. Here are two examples of the folder path to the Outlook Secure Temp folder. The paths will not be the same on yours. When you open an attachment directly in Outlook, a temporary copy of the file is created in the Outlook Secure Temp folder. When you close the file and its email, the temporary file stays there.

When you close Outlook, the temporary file should disappear. One of mine contains 10 files dated since Dec so perhaps Outlook does not clean them out properly every time or perhaps each file represents an occasion on which Outlook or my OS crashed while a file was open. Perhaps this is how this “folder” can get full. I have been running some tests.

As I understand it, Outlook invokes the installed antimalware application to scan the attachment before it opens. However, my antimalware application creates logs of its scans [even scans of individual files] and no entries have been made for the attachments I have been testing. So I am going to stick with my existing procedure for attachments This thread is only of use to Office users rather than general Windows users so I asked a Moderator to move it to the Office forum.
