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 and ScreenSaveActive.

You want to make sure the value for ScreenSaverIsSecure and ScreenSaveActive is 0 (zero).

Exit regedit; you’re done!

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop]

Delete the "ScreenSaverIsSecure" value.

If this comes back, you may have to use Group Policy Editor.

OR

Disable the lock workstation button

[HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Policies \System]
DisableLockWorkstation = 1

Ultimate lock down
