Given that supposedly windows 7 installs all features on all versions, and picks the version from the CD key, is there a way to upgrade the version without doing an install of some kind, but just changing the OEM key from home premium to ultimate? Is there some trick to doing so? or do I have to do some kind of an install? Basically what I want to do is an easy upgrade from home premium to ultimate without having to reinstall any drivers, any programs, etc... Thanks
if u already activated Windows 7 using a loader or biosmod you can start the setup while being booted in windows Choose upgrade, then upgrade, then just install a OEMSLP key for Ultimate
