How to Change Background for User from Adm Account

Okay this is not really work related but we’re having fun today in the office.

FL beat OU last night and we have a very big OU fan in the office, so we’ve been redecorating this office. We’d like to extend that to his computer as well.

First we were able to change his log in screen background but we are unable to change his desktop background (XP SP2 btw) and we are looking for a way to do it.

We went into the reg for the first one, HKU\default\desktop\wallpaper (which was our login screen not his desktop background). Any help playing this little trick would be helpful (don’t worry we’ll change it back Monday after he comes back in).
