Thanks to "Rick H." for posting this tips for Vista:
--------
Just a quick note to say that you can change the default search provider in IE7. Click the drop-down arrow at the edge of the search box in the upper right. Select "Find more providers" and see if your favorite is available (most are). Then click the drop-down again and choose Change Search Defaults.
For the admin popups (It's called UAP or UAC depending who you ask), run secpol.msc. Navigate to Local Policies->Security Options. Set UAC:Behavior of Elevation Prompt for Admins to "No Prompt" and UAC:Run All Admins in Approval Mode to disabled. (Use at your own risk!)
---------
I'm not sure how you figured out the UAC issue but what a life-saver that is for me. Thanks! Now if someone could figure out how to get my transparent windows back I'll be all set.
