Obviously a lot of people cried fake when those screenshots purporting to show Windows 7 Ultimate popped up -- possibly because they looked a lot like rebadged Vista screens -- so the blogger who originally posted the images has followed up with a video for proof. And we do have to say, if this is fake, someone put a hell of a lot of work into pulling it off, from creating a new bootup screen to hacking the source code to adding fresh Media Center options. ThinkNext tells us that this release -- known as Milestone 1 -- expires in May of this year, although if Redmond and its team of crack Enemy of the State-types have anything to say about it, this particular blog will not be getting another preview copy next time around. Video after the break.
