Force the Use of Automatic Logon (Windows 2000/XP) Popular

Normally when a Windows machine is configured to automatically logon to a specified account users can bypass this and enter alternate account information. This tweak forces the machine to auto logon and to ignore any bypass attempts.

This tweak can be easily applied using WinGuides Tweak Manager.
