Hey all Is it possible to upgrade a windows 7 home premium to Professional or ultimate without reinstall? I allready asked my friend, why not just do is a reinstall. But he really would like to use the anytime upgrader. But he can't afford to buy a upgrade key. Regards from denmark
Thank you AlexAlba I will try to seach the net, and hopefully find some valid keys. Once again, thank you for your time. . Cheers from denmark
AlexAlba, advice is wrong if you have retail or OEM:NONE SLP then you need to Buy upgrade key. If you are activated via OEM:SLP 2.1 then you can just use key from Windows-7-OEM-SLP-Key-Collection
Wrong; you can use oem:slp key as valid anytime upgrade key on a system with oem:slp activation without re-install.
