Access to Desktop is Denied

[Guest]

OK, I did something really stupid. I accidentally locked myself out of the
desktop in XP by changing the owner to myself in Vista. This was so I could
save something to my XP desktop.

How do I change the owner back to my account in XP? I'm an admin, and
there's no other users on the XP installation.

All bets are off as you used VISTA, but see if the following solves your
problem.
