Windows Server 2012 R2, codenamed "Windows Server Blue", is the tenth version of the Windows Server operating system by Microsoft, as part of the Windows NT family of operating systems. It was unveiled on June 3, 2013, at TechEd North America,[5] and released on October 18 of the same year.[2] It is the successor to Windows Server 2012, and is based on the Windows 8.1 codebase.
Windows Server 2012 R2 removed support for processors without CMPXCHG16b, PrefetchW, LAHF and SAHF.
A further update, formally designated Windows Server 2012 R2 Update, was released in April 2014.[6] It is a cumulative set of security, critical and other updates.[7] Windows Server 2012 R2, like previous versions of Windows Server before it and versions after it, is only compatible with 64-bit processors.
Windows Server 2012 R2 was succeeded by Windows Server 2016, which is derived from the Windows 10 codebase.
