Little shrewdness : Windows 8 Build 7850, don't have BuildGUID, instead Windows 7 yes, this means that someone has removed the tracing before the leak, so the leak of build 7955 there be.
Once again: The buildGUID is NOT fffffff.... because it's blanked out by the leaker, it's fffffff.... because in Windows 8 it just IS ffffffff. @ davibs: vlad62 never said he's planning a leak.
No Just install as normal Windows 7. You do not need to change the date No timebomb No watermark You can activate as Windows 7 Enterprise
oke, I have installed 7850 , run WOAT_v3.2, then pressed C (for KMS Activation) after that I have to use Y (proceed with activation) or N detect OS and install VL Key? because I tried both and none worked... it gave me some errors with "no file found" or something like that
