Lol, That's just not cricket old chap, the first thing i do after installing win2k or XP is go into services and disable useless programs that microsoft has decided i need, ie Messenger, remote registry, remote install and helpsv. I have been doing this for years and it has not messed anything up.
Because i'm running process explorer i have a good idea of what rubbish is running in the background and at startup and Regprot is a simple program that lets you know when something is being added to the registry for startup. Using these little freeware apps keeps the machine cleaner than it normally would be without them and I would not suggest anything that i didn't think was the mutts nuts.
