The floodgates are truly open now. Yesterday we reported that an English version of Windows 8.1 Pro (x64) RTM had leaked, but with a corrupted install.wim file (that could be repaired). Today two 'untouched' original ISO's have already leaked online, this time both the x64 and x86 versions.
The leak originates from Russian leaker WZOR, and Windows Server 2012 R2, Essentials, Enterprise, Hyper-V Server and Foundation Storage will also make their way to torrent sites today, as well as the Russian versions and language packs.
The leak descriptions come with full build strings (6.3.9600.16384.WINBLUE_RTM.130821-1623 for the x64 ISO) and emphasise that they are Microsoft images, not frankenbuilds or modified (as yesterday) in any way.
