Best Services guide ive seen Abaddon!

http://www.tweakhound.com/xp/xptweaks/supertweaks1.htm

For the gamer wanting to maximize winXP performance. Even has a "Bad" tweaks section to save Abaddon from going "whats this do" hehehe

That site is great, but along the same lines here is another site that
gives a breakdown on services

Thanks guys.

I made my mistake with services because XP Service Pack 2 adds a number of other services not listed in standard tweak guides. One of the ones I disabled made it impossible for me to access programs on my computer (including the services.msc file). I have gone back to XP Service Pack 1, and applied the tweaks from Black Viper, which are the ones I was using before.
