A few years ago I purchased my computer from an small online site that came with version of windows xp. Eventually I had to format my drive and thus lost my copy of windows & it never came with a recovery disk. Being a poor college student I just got a pirated version YARRRRRR
So I have a pirated version of XP professional SP1 on my system, but I want to put a legit version on it now since I'm tired of not being able to update without fear. Can I just buy XP home upgrade? or XP professional upgrade? Or do I have to get the full version? Thanks!!!
