Windows Server 2012 build 8400 is the official Release Candidate build of Windows Server 2012, which was released on 31 May 2012[1] along with its client counterpart. It was also additionally released in the form of a set of Repair Content Packages, which are used by DISM /Cleanup-Image /RestoreHealth to repair an existing Windows installation, making it one of the few remaining server builds to be released with a 32-bit counterpart after support for the x86 architecture was dropped with the release of Windows Server 2008 R2.
