I recently installed Win 7 64 Bit Built 72364, but it refusedthe 64 Bit Product Keys I received from MS. Can you guys help, please!

Okay,W7RC is build 7100. Download it from the official MS site, reinstall over whatever it is you have installed, and you shouldn't have a problem.Hope that helps....Regards from the Valley of the Sun.

Build 7264 doesn't accept the RC keys.You might be able to find a hack on the Web that would force 7264 to activate with one of the RC keys, but I doubt that the moderators would be pleased to see it (or a link to it) posted here.In fact, builds 7000 (the public beta) and 7100 (the RC) are the only ones deemed suitable for discussion here:http://social.technet.microsoft.com/Forums/en/w7itprogeneral/thread/fd2d96ae-aaa3-49c1-a287-0bddbd21c425

Windows 7 Unofficial Build is not supported on the forum. Thanks.
