By its very nature, XP comes with a feature called System Restore. In the event you experience strange performance from your computers operating system, System Restore, allows you to revert back to an earlier date and time when your computer was working normally. By default, XP creates a new restore point on its own whenever you turn your computer back on after it has been shut down.
You should set a Restore Point before editing the Registry, downloading software updates from the Internet, installing new hardware or software, or updating drivers, etc. more

Over time it seems that Windows XP just gets bogged down with stuff we don't want or use. In my search to improve system performance, one way to squeeze more performance out of XP is to disable the last access/update feature.

This process takes a considerable amount of resources away from your computer, so it just might make sense to disable this feature. Disabled or not, you will still have access to your last modified information for files and folders, and remember, if you don't like the change, or you see no significant value after the change, you can always go and change it back to its default setting. more
