Defrag
WinXp's Defrag is very different than Win98. It uses a slimmed down version of Diskeeper.
1) double-click My Computer
2) right-click on the drive you want to run defrag on and select Properties
3) click the Tools tab and click "Defragment now . . ."
4) this will start up Diskeeper. Click the drive you want to defrag, then click "Analyze"
5) click "Defragment"
