User Profiles Question

I have a question regarding user profiles in XP. I have 3 profiles plus the Guest Account setup on my machine.

My wife installed Yahoo stuff under her profile. I know how to get rid of the icons and stuff from the desktop and start menu. But it also installed a whole bunch of crap on my toolbar in IE. Is there any way to get rid of the stuff in all of the profiles but hers? She also installed Incredimail, and it stole the default mail association from Outlook within my profile, even though she installed it under her profile.

Is there anyway to fix this, or prevent this from happening? I thought the whole idea of having seperate profiles was to be able to have unique settings for each user.

Any help would be appreciated.

Thanks

To fix your outlook problem, it should realize that it's not the default when you launch it, and ask to be the default.
