Windows 8 build 8331 (winmain)

Windows 8 build 8331 (winmain) is a pre-Release Preview build of Windows 8. A screenshot of this build was released onto the BetaArchive Discord in 2018-09-09, however the screenshot of this build is fake because it uses the same hash ID as build 8331.fbl_loc.120425-2034. This build was confirmed by an old (unused) WinJS 1.0 in the Windows Store infrastructure.
