Windows Server 2012 is the server counterpart of Windows 8. It replaces Windows Server 2008 R2 and was replaced by Windows Server 2012 R2. It reached RTM on 1 August 2012. Support for the IA-64 architecture was dropped with this release.

This is the first version of Windows Server to drop support for processors without PAE, SSE2 and NX, as running on these processors will display a black screen with error code 0x5D. This is the last version of Windows Server to support processors without the CMPXCHG16b, PrefetchW and LAHF/SAHF instructions. It is the first server release of Windows to drop the traditional Service Pack mechanism in favor of releasing updates on a continual basis in smaller chunks.
