Windows Server 2016 build 9841 is the first official Technical Preview build of Windows Server 2016, which was released on 1 October 2014 along with its client counterpart.[1]

It is the first known server build to use flight-signing, a functionality which prevents the operating system from booting once the timebomb is triggered.
