your all better off checking out blackviper.com (google it) for a detailed list of XP services , what they do, and if/why you need them. manually disable only the services you need to, keep the ones you do. there's a few GOOD speedup tweaks, reg files, etc. not to sweat the name, it aint a 'hacker' site or nuthin, I wouldnt send you there. This guy, is awesome for XP tweaks... Ive used his tutorials since he got online.
