Windows 8 build 8331 (winmain)

This build was confirmed by an old (unused) WinJS 1.0 in the windows store infrastructure. Pictures of Windows 8 build 8331.winmain.120425-1916 were released onto BetaArchive Discord on 2018-09-09, however the screenshot of this build is fake because it has the same hash ID as build 8331.fbl_loc.120425-2034.
