You're in the wrong place.
Click Start - Run, type in MSCONFIG, then click OK - "Startup" tab. Everything listed there with a checkmark next to it is automatically loading during startup and running in the background. Other than
ScanRegistry
SystemTray
StateMgr (Windows ME only)
Antivirus program entries
Firewall program entries
very few others, if any, need to load and run.
This site will assist you in trimming down the startup list of unnecessary running entries.
