Why don't you roll them back to XP? I assume there are other laptops running XP arround? That is what we do, just to keep a certain consitency in our computer park, and saves us a lot of hassle, specially in a networked community/school. Sorry, you must have noticed that, hence your question. .
Anyway, I would love to hear an answer to your question, interesting.... I will be lurking :-)!
Good luck!
