I have the "leaked" version of build 7000 64 bit installed. I used the patch mentioned on this site to remove watermark, "Send Feedback", and activate the OS. All is working well, including updates, it shows the OS is genuine, and activated. WINVER shows it will expire 7/1/2009 6:59PM. Anybody have any idea what the advantage will be to get an "official" key when they are released this afternoon? I'm not sure I'm going to be available to get one.
