The Windows 7 product keys given away by Microsoft to Windows 7 Release Candidate (RC) downloaders appear to be from a pool of same 15 sets of product keys, similar to what’s happen during public availability of Windows 7 Beta where everybody gets the same sets of Windows 7 Beta product keys, after massive interest crashed the Microsoft servers.
After downloading and installing the 32-bit and 64-bit Windows 7 RC x86 and x64 DVD ISO images, the default activation grace period of 30 days applies.
