Windows Server 2012 build 7904

Windows Server 2012 build 7904 is a build of Windows Server 2012, which was shared on the BetaWiki Discord server on 30 September 2021. Windows Basic is now used as the default theme instead of Windows Classic. Aero Lite has gained Metro-style window metrics, but only when DWM is initialized. This is the last known build to contain the blue-green gradient background present since build 7788. It would be later replaced with a plain green wallpaper featuring a wordoku puzzle in build 7959.

Start screen accent
