Yes there are a lot of things in services that use resources & they do not apply to a lot of peoples needs such as "Uninteruptable power supply" or "wirless zero configuration", if I need them I will tick them!!
Some others I have unticked:
Automatic updates.
Both Smart card resources.
I am running ATI card so have unticked:
ATI Hotkey poller.
I will have to download info
later on the various resources to see what else I can untick!!
Let me know how you go!
Cheers.
