Well, you should try to figure out what each of them actually
do. Some of them, like explorer.exe and taskmgr.exe, should be obvious. For others, you can try searching your hard drive to find where the .exe file actually lives. If it's in the Windows/System32 directory, odds are you need it.
If in doubt, you can also try typing the name of the process into Google and see what comes up.
A good resource for this kind of stuff is
Black Viper's site. He goes into detail about what all the windows services do and which ones you can safely turn off to save resources.
