This is a great way to speed up your windows xp computer, it's free and the tool is already installed on your computer. As you probably already know computers slow down over time and get clogged up. So a great way to un-clog your computer and keep it healthy is to do a Disk Cleanup.

Disk Fragmentation:
Due to the way hard-disks work, it's important to do disk defragmentation. It's a long word but all it does is piece back your computers files so they can be used in a more efficient way - thus improving your systems over all performance.

Turn Off Disk-indexing
Yet another way to speed up your computer is by disabling disk-indexing and installing GoogleDesktop which is a much faster search tool and has some other handy features.
To disable disk-indexing go to My Computer, right-click on your hard drive and select "Properties." A new box will pop up, and at the bottom right above the "OK" and "Cancel" buttons there will be a check box right beside those words "Allow Indexing Service to index this disk for fast file searching." Uncheck that box, then click "OK."
