I don't know why I didn't know about this before since it fixes so many of the things I HATE about XP.
- Turn off baloon notifications.
- Stop apps from stealing focus (i.e.: typing in MS word and another app pops up requesting data and you are now typing in the app that popped up).
- Remove that bluetooth icon from your desktop.
You can change a whole host of other things too.
I'm finally getting revenge on some of the thing that drive me the most crazy in XP.
