I had a PC recently. It had Windows 7 on it and I eventually bought a Windows 8 upgrade key. Then the computer died and I switched to Mac. I have an old different PC running Windows XP. Since the original computer is dead, is it possible to use the same key again? When I tried just now it said I can't use an upgrade key to install windows 8, which doesn't make any sense to me.
