And we've already told him it's not adviseable on Windoze....
Not advisable? Vista Ultimate runs fine without it and the dozens of other Microsoft crapware apps that it installs. Here's how it goes down:
Do your Boot Camp dealio. Get everything how you want it and then reboot into OS X.
(I don't know if you need MacFUSE for this, but I have it.)
Now open your Windows partition from OS X and navigate to the Program Files folder. Drag anything that you don't want/need to the OS X trash and let it get rid of it. When you restart Windows, none of these apps will have "reinstalled" themselves and Windows doesn't complain because the files were not only deleted, but were wiped from the plane of existence as far as Windows is concerned. It has no knowledge whatsoever of the apps that you deleted, so it can't create callbacks to something that virtually never existed.
I got rid of all of the Windows games, Movie Maker, Player, the photo apps, and everything that didn't involve drivers. Vista now runs very well. Go figure.
