I do not wish my screensaver to lock my computer.

In Windows XP, it really annoys me when my computer idles for a few minutes and then the screen locks. I try to be careful not to leave my laptop lying around, so I prefer my screensaver not to be password-protected.

In order to make it so that your computer won’t lock itself after a few minutes, do this:
Run ‘regedit’ to edit your registry
Navigate down the tree to HKEY_CURRENT_USER > Software Policies > Microsoft > Windows > Control Panel > Desktop and look for an entry ScreenSaverIsSecure. You want to make sure the value for ScreenSaverIsSecure is 0 (zero).
Exit regedit; you’re done!
