I recently borrowed a copy of vista Ultimate from friend and only have the 30
days to activate. I want to keep all my data that I have from my recent
upgrade from XP Pro. I am most likely going to buy a version of Premium to
get a geniune copy of vista. What do I need to do?- Buy a full version of
Premium, or an OEM version, or have to reinstall XP Pro then upgrade back to
Premium. Any help would be appreciated.
