Product Description :


A second release, Windows Server 2008 R2, was released on October 22, 2009.[34] Retail availability began September 14, 2009. Windows Server 2008 R2 reached the RTM milestone on July 22, 2009.Like Windows 7, it is built on Windows NT 6.1. New features include new virtualization features, new Active Directory features, IIS 7.5, and support for 256 logical processors. Support for 32-bit-only processors (IA-32) has been removed. On July 22, 2009, Microsoft officially announced that they had released both Windows Server 2008 R2 and Windows 7 to manufacturing. Windows Server 2008 R2 was generally available for download from MSDN and Technet on August 19 and for retail purchase from October 22, 2009.




Compared to its predecessor, most editions of Windows Server 2008 are available in x86-64 and IA-32 versions. These editions come in two DVDs: One for installing the IA-32 variant and the other for x64. Windows Server 2008 for Itanium-based Systems supports IA-64 processors. Microsoft has optimized the IA-64 version for high-workload scenarios like database servers and Line of Business (LOB) applications. As such, it is not optimized for use as a file server or media server. Microsoft has announced that Windows Server 2008 is the last 32-bit Windows server operating system.[28] Editions of Windows Server 2008 include:

Windows Server 2008 Standard (IA-32 and x86-64)
Windows Server 2008 Enterprise (IA-32 and x86-64)
Windows Server 2008 Datacenter (IA-32 and x86-64)
Windows HPC Server 2008 (Codenamed "Socrates") (replacing Windows Compute Cluster Server)
Windows Web Server 2008 (IA-32 and x86-64)
Windows Storage Server 2008 (Codenamed "Magni") (IA-32 and x86-64)
Windows Small Business Server 2008 (Codenamed "Cougar") (x86-64) for small businesses
Windows Essential Business Server 2008 (Codenamed "Centro") (x86-64) for medium-sized businesses
Windows Server 2008 for Itanium-based Systems
Windows Server 2008 Foundation (Codenamed "Lima") (x86-64) for OEMs only

The Microsoft Imagine program, known as DreamSpark at the time, used to provide verified students with the 32-bit variant of Windows Server 2008 Standard Edition, but the version has since then been removed. However, they still provide the R2 release.

The Server Core feature is available in the Web, Standard, Enterprise and Datacenter editions.

Service Pack:


Microsoft occasionally releases service packs for its Windows operating systems to fix bugs and also add new features.

Because Windows Server 2008 is based on the Windows NT 6.0 Service Pack 1 kernel, the RTM release is considered to be Service Pack 1; accordingly, the first service pack is called Service Pack 2. Announced on October 24, 2008, this service pack contains the same changes and improvements as the Windows Vista Service Pack 2, as well as the final release of Hyper-V 1.0, and an approximate 10% reduction in power usage.

The first SP2 beta build was sent out in October 2008, a public beta arrived in December 2008, and an RC-escrow build was given to testers in January 2009. Windows Vista and Windows Server 2008 share a single service pack binary, reflecting the fact that their code bases were joined with the release of Server 2008. On May 26, 2009, Service Pack 2 was ready for release. It is now available in Windows Update.
