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. It's also the last available Windows Server build as of 2024 to use the Windows 7 sound scheme.
