Windows Server 2012 build 7850 is the official Milestone 1 build of Windows Server 2012, which was uploaded to BetaArchive on 17 January 2015.[1] Due to its earliness, this build still uses Windows Server 2008 R2 branding in many areas and still uses kernel version 6.1.

This is the latest available build to use the Windows Classic theme by default, and it is more functional here than in its client counterpart (until Aero theme is applied).
