XPs version of Windows 2000's Ctrl-Alt-Del
Version Compatibility: Visual Basic 6
All you have to do is make the executable, then create a shortcut on your desktop linking it to a shortcut keycode like Ctrl-Alt-End or something. This way you can quickly switch users or even open the System Info dialog without having to change your XP settings for the logon screen.
Note that this application will work on other windows versions, but is particurlarly useful for XP because it provides functionality that otherwise would not be there.
