I forgot my Screen Saver Password
Have you ever forgotten your screen saver password, not being able to return
to "normal operation" in Windows 9x? Well, there is a way to
completely delete the screen saver password, allowing you to get your system
back. Fire up Regedit and go to:
HKEY_USERS\.Default\Control Panel\desktop
In the right hand pane look for the "ScreenSave_Data"
String value.
Highlight it and hit the Delete key.
