I had a laptop last year that the screen busted on.  I ended up parting out the entire laptop.  I kept the sticker for the XP license for XP home.  Am I able to use it to upgrade to Vista on my desktop?  It is currently running Win2k, but I don't think there is an upgrade path for it to Vista.  Will it only upgrade to the basic Vista?  I'd prefer to have business or ultimate.
