Stephen reports of an early Build 7504.0.amdfre.winmain.090528-xxxx of Windows 8, it seems, Microsoft has already started compiling builds for Windows 8! Just to note, the early builds still always have the labeling from the OS before it, so instead of saying Windows 8, this would still say Windows 7 (download). Technically, Windows 8 would be either 6.2 or 6.1.1, but strange things happen during development and this may not be the tell-tale sign of a fake.
