Alright, my brother had a friend of his do something with his computer. I don't know if it was to build a new one, fix it or whatever -- Anyhow, the guy ends up putting a copy of Windows XP on the machine which just so happened to be a pirated copy of some sort. Well all the while my brother actually has had a legit copy of his own that he purchased at home. He asked me if there was anyway he could install his Windows Home Edition over what ever is on there right now without having to reformat that drive. He doesn't want, nor does he know how to back up all his data and reformat. So, OT... Is there a way?
