I'm trying to reformatt and reinstall Windows XP Home on my GF's computer. She has a CD Key for Home, but I can't find the disc for the life of me. No big deal, so I downloaded a copy (nothing illegal about that) and it won't take the key. I try a different version of XPH, still no go. I've tried OEM and retail verisons, no SP and SP2, Still nothing.
Anyone have any ideas? Anyway to find out what version of Windows will work with a certain key?
This is driving me nuts!
