If I get Win 7 Professional Upgrade disk, does it contain the other versions of the OS as well? Or is specific to whatever version you get? For example, with my Win 7 Profession Upgrade disk I want to upgrade my sister's Home Basic laptop to Win 7 Starter/Home Premium and my parent's Home Premium to Win 7 Home Premium. Would I be able to this with my one disk?
Would I be able to use a Full version of Win 7 to upgrade any exiting computer using their Keys?
