i wouldn't bother if i was you, i tried one and icons where goin missin, luckily enough system restore saved the day, but it could cause seriouser problems.
If you do, back up and keep your back ups for a few weeks until you know for sure everythin is ok, you may think everythin is ok then you come to do something and a icon etc is missing.
My LAN connection icon was getting deleted with mine, so i couldn't switch my XP firewall on and off etc.
i used WinCleaner 2000, but wouldn't bother with the likes again
GOOD LUCK!!!
