Re-installing must surely be an attractive option, I'd have thought. You've no control over the contents of these computers at all as things stand, even if you do end up with administrator rights.

Getting a clean XP CD that'll take your existing valid XP license codes from the Microsoft stickers is a minor hardship in the long run.
