Windows Server R2 is the fifth version of the Windows Server operating system produced by Microsoft and released as part of the Windows NT family of operating systems.
It was released to manufacturing on July 22, , [11] and became generally available on October 22, , shortly after the completion of Windows 7. Enhancements in Windows Server R2 include new functionality for Active Directory , new virtualization and management features, version 7.
It is built on the same kernel used with the client-oriented Windows 7 , and is the first server operating system released by Microsoft to exclusively support bit processors, a move which was followed by the consumer-oriented Windows 11 in Windows Server R2 is also the last version of Windows to support Itanium processors; its successor, Windows Server , supports x64 processors only.
A home server variant called Windows Home Server was also released. Microsoft is no longer providing security updates and technical support for Windows Server R2 RTM since April 9, , and Service Pack 1 must be installed to continue receiving support and updates on any given Windows operating system. Official mainstream support for Windows Server and R2 ended on January 13, , and extended support ended on January 14, Two days later, the beta was released to the public via the Microsoft Download Center.
According to Windows Server Blog , [18] the following are the dates of the year when Microsoft Windows Server R2 has been made available to various distribution channels:.
Additionally, qualifying students have been able to download Windows Server R2 Standard edition in 15 languages from the Microsoft Imagine program known as DreamSpark at the time. Microsoft has announced that Server R2 will be the last version of Windows supporting the Itanium architecture, with its extended support ending earlier than for the regular non-Itanium edition or “until July 10, A reviewer guide published by the company describes several areas of improvement in R2.
IIS 7. Since many zones use a different algorithm — including the root zone — this means that in reality Windows still can’t serve as a recursive resolver. The DHCP server runs in the context of the Network Service account which has fewer privileges to reduce potential damage if compromised. Windows Server R2 supports up to 64 physical processors [26] or up to logical processors per system.
Only the Datacenter and Itanium editions can take advantage of the capability of 64 physical processors.
Enterprise, the next-highest edition after those two, can only use 8. Server Core includes a subset of the. When raising the forest functional level, the Active Directory recycle bin feature is available and can be enabled using the Active Directory Module for PowerShell.
Support for the RTM version of Windows Server R2 ended on April 9, , [9] [10] and users will not be able to receive further security updates for the operating system, due to new policies requiring Service Pack 1 [31] to continue to be supported with security updates, lasting until the end of support lifecycle for that Windows operating system.
The host without the latest Windows Server R2 service pack installed is vulnerable to viruses and multiple security attacks. On January 13, , Windows Server R2 exited mainstream support and entered the extended support phase; Microsoft continued to provide security updates every month for Windows Server R2, however, free technical support, warranty claims, and design changes were no longer being offered.
Extended support ended on January 14, , about less than eleven years after the release of Windows Server R2. In August , researchers reported that “all modern versions of Microsoft Windows” may be at risk for “critical” system compromise due to design flaws of hardware device drivers from multiple providers.
Dynamic Memory makes it possible for a VM to only allocate as much physical RAM as is needed temporarily for its execution. System requirements for Windows Server R2 are as follows: [37].

Microsoft Windows is the name of several families of computer software operating systems created by Microsoft. All versions of Microsoft Windows are commercial proprietary software. Windows Embedded Compact Windows CE is a variation of Microsoft’s Windows operating system for minimalistic computers and embedded systems. Windows CE is a distinctly different kernel, rather than a trimmed-down version of desktop Windows.
Windows Mobile is Microsoft’s discontinued line of operating systems for smartphones. Windows Phone is Microsoft’s discontinued line of operating systems for smartphones. The Windows NT kernel powers all recent Windows operating systems.
Windows Embedded CE 6. Installing Windows requires an internal or external optical drive, or a USB flash drive. A keyboard and mouse are the recommended input devices, though some versions support a touchscreen.
For operating systems prior to Vista, an optical drive must be capable of reading CD media, while in Windows Vista onwards, such a drive must be DVD-compatible. The drive may be detached after installing Windows. Maximum limits on physical memory RAM that Windows can address vary depending on both the Windows version and between IA and x64 versions.

Windows NT is a proprietary graphical operating system produced by Microsoft , the first version of which was released on July 27, It is a processor-independent, multiprocessing and multi-user operating system. It was a commercially focused operating system intended to complement consumer versions of Windows that were based on MS-DOS including Windows 1. Gradually, the Windows NT family was expanded into Microsoft’s general-purpose operating system product line for all personal computers , deprecating the Windows 9x family.
Starting with Windows , [6] “NT” was removed from the product name and is only included in the product version string along with several low-level places within the system. NT was the first purely bit version of Windows, whereas its consumer-oriented counterparts, Windows 3. It is a multi-architecture operating system. One of the main purposes of NT is hardware and software portability.
NT has supported per-object file, function, and role access control lists allowing a rich set of security permissions to be applied to systems and services. Windows NT 3. Its companion product, Windows 3. The full preemptive multitasking kernel could interrupt running tasks to schedule other tasks, without relying on user programs to voluntarily give up control of the CPU, as in Windows 3.
Notably, in Windows NT 3. In Windows NT 4, the video, server, and printer spooler subsystems were moved into kernel mode. Windows NT also allows for other installable file systems; since versions 3. Windows NT introduced its own driver model, the Windows NT driver model, and is incompatible with older driver frameworks. Windows 3. This decision caused tension between Microsoft and IBM and the collaboration ultimately fell apart.
Like VMS, [23] Windows NT’s kernel mode code distinguishes between the “kernel”, whose primary purpose is to implement processor- and architecture-dependent functions, and the “executive”.
This was designed as a modified microkernel , as the Windows NT kernel was influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, [25] but does not meet all of the criteria of a pure microkernel. Both the kernel and the executive are linked together into the single loaded module ntoskrnl. Routines from each are directly accessible, as for example from kernel-mode device drivers. Windows NT was one of the earliest operating systems to use Unicode internally.
Windows NT 4. The first release was given version number 3. Also the Novell IPX protocol was apparently licensed only to 3. The NT version number is not now generally used for marketing purposes, but is still used internally, and said to reflect the degree of changes to the core of the operating system.
Starting with Windows 8. If an application is not manifested for Windows 8. Assembly language is avoided where possible because it would impede portability. In order to prevent Intel x86 -specific code from slipping into the operating system by developers used to developing on x86 chips, Windows NT 3. Both systems were designed internally at Microsoft. Only two of the Windows NT 4. All of the other ports done by third parties Motorola, Intergraph, etc.
Microsoft demonstrated a preliminary version of Windows version 6. According to Microsoft, it is a common misconception that the Xbox and Xbox use a modified Windows kernel.
In reality, the Xbox operating system was built from scratch but implements a subset of Windows APIs. Windows 11 is the first non-server version of Windows NT to not support bit platforms. The minimum hardware specification required to run each release of the professional workstation version of Windows NT has been fairly slow-moving until the 6.
