Windows Server 2008 R2 is a serveroperating system produced by Microsoft. It was released to manufacturing on July 22, 2009 and became generally available on October 22, 2009.
Enhancements include new functionality for Active Directory, new virtualization and management features, version 7.5 of the Internet Information Servicesweb server and support for up to 256 logical processors. It is built on the same kernel used with the client-oriented Windows 7, and is the first 64-bit–only server operating system released from Microsoft.
Seven editions of Windows Server 2008 R2 were released: Foundation, Standard, Enterprise, Datacenter, Web, HPC Server and Itanium, as well as Windows Storage Server 2008 R2. A home server variant called Windows Home Server 2011 was also released. It was succeeded by Windows Server 2012.
Microsoft introduced Windows Server 2008 R2 at the 2008 Professional Developers Conference as the server variant of Windows 7.
On January 7, 2009, a beta release of Windows Server 2008 R2 was made available to subscribers of Microsoft's TechNet and MSDN programs, as well as those participating in the Microsoft Connect program for Windows 7. Two days later, the beta was released to the public via the Microsoft Download Center.
On April 30, 2009, the release candidate was made available to subscribers of TechNet and MSDN. On May 5, 2009, the release candidate was made available to the general public via the Microsoft download center.

According to Windows Server Blog, the following are the dates of the year 2009 when Microsoft Windows Server 2008 R2 has been made available to various distribution channels:
- OEMs received Windows Server 2008 R2 in English and all language packs on July 29. The remaining languages were available around August 11.
- Independent software vendor (ISV) and independent hardware vendor (IHV) partners have been able to download Windows Server 2008 R2 from MSDN starting on August 14.
- IT professionals with TechNet subscriptions were able to download Windows Server 2008 R2 and obtain product keys for English, French, German, Italian, and Spanish variants beginning August 14 and all remaining languages beginning August 21.
- Developers with MSDN subscriptions have been able to download and obtain product keys for Windows Server 2008 R2 in English, French, German, Italian, and Spanish starting August 14 and all remaining languages starting August 21.
- Microsoft Partner Program (MPP) gold/certified members were able to download Windows Server 2008 R2 through the MPP portal on August 19.
- Volume licensing customers with an existing Software Assurance (SA) contracts were able to download Windows Server 2008 R2 on August 19 via the Volume License Service Center.
- Volume licensing customers without an SA were able to purchase Windows Server 2008 R2 through volume licensing by September 1.
Additionally, qualifying students have been able to download Windows Server 2008 R2 Standard edition in 15 languages from the Microsoft Imagine program (known as DreamSpark at the time).
Microsoft has announced that Server 2008 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, 2018.'
A reviewer guide published by the company describes several areas of improvement in R2. These include new virtualization capabilities (Live Migration, Cluster Shared Volumes using Failover Clustering and Hyper-V), reduced power consumption, a new set of management tools and new Active Directory capabilities such as a 'recycle bin' for deleted objects. IIS 7.5 has been added to this release which also includes updated FTP server services. Security enhancements include encrypted clientless authenticated VPN services through DirectAccess for clients using Windows 7, and the addition of DNSSEC support for DNS Server Service. Even though DNSSEC as such is supported, only one signature algorithm is available: #5 / RSA/SHA-1. 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 supports a large number of enhancements such as MAC address-based control filtering, converting active leases into reservations or Link Layer based filters, DHCppP Name protection for non-Windows machines to prevent name squatting, better performance through aggressive lease database caching, DHCP activity logging, auto-population of certain network interface fields, a wizard for split-scope configuration, DHCP Server role migration using WSMT, support for DHCPv6 Option 15 (User Class) and Option 32 (Information Refresh Time). The DHCP server runs in the context of the Network Service account which has fewer privileges to reduce potential damage if compromised.
Windows Server 2008 R2 supports up to 64 physical processors or up to 256 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.) When deployed in a file server role, new File Classification Infrastructure services allow files to be stored on designated servers in the enterprise based on business naming conventions, relevance to business processes and overall corporate policies.
Server Core includes a subset of the .NET Framework, so that some applications (including ASP.NET web sites and Windows PowerShell 2.0) can be used.
Performance improvement was a major area of focus for this release; Microsoft has stated that work was done to decrease boot time, improve the efficiency of I/O operations while using less processing power, and generally improve the speed of storage devices, especially iSCSI.
Active Directory has several new features when raising the forest and domain functional levels to Windows Server 2008 R2: Two added features are Authentication Mechanism Assurance and Automatic SPN Management. 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.
On February 9, 2011, Microsoft officially released Service Pack 1 (SP1) for Windows 7 and Windows Server 2008 R2 to OEM partners. Apart from bug fixes, it introduces two new major functions, RemoteFX and Dynamic Memory. RemoteFX enables the use of graphics hardware support for 3D graphics in a Hyper-V based VM. Dynamic Memory makes it possible for a VM to only allocate as much physical RAM as is needed temporarily for its execution. On February 16, SP1 became available for MSDN and TechNet subscribers as well as volume licensing customers. As of February 22, SP1 is generally available for download via the Microsoft Download Center and available on Windows Update.
