You have a Vista generic OEM disk, Stu? I don't know of anyone that does as
it has not been released yet.
The current understanding of generic OEM full version disks is that they can
only be used for a clean install to a formatted disk. In the case of XP, one
could do a repair install to an existing system with an OEM disk, but not
use it to upgrade from Win2000, NT4, Win98, or WinME.
