What is that in your Windows XP services?

If you've dug deep into your Windows XP system, you'd know that there are things called "Services" which are software processes running in the background and taking up RAM usage. Some of them are essential, others are dumped there when you install software. If you've busy installing software, you'll soon find out you don't know what the services are for anymore. This website provides a handy guide to the services running and recommends which of these may be disabled. Word of caution here... do so at your own risk.
