Using Windows Task Manager (WinXP) I noticed my available physical RAM was a bit less than I expected so I clicked on the current processes and was shocked to see lots of stuff running I wasn't aware of. The biggest problem being that I don't know what 70% of them are. Is there a good way to find out what these little apps are and if I really need them? Furthermore, if some are not necessary is there a universal way to see that they don't automatically run in the future? -or will I need to attack each one individually?
