Windows NT/2K provides Registry settings that can be set so that a user is automatically logged in the next time the system would otherwise put up the logon dialog box. However, the Registry values are hidden very deep, and are a pain to configure. This program, Autologon, will do the Registry configuration for you, and allow you to enable and disable auto-logon when you want.
Autologon is easy enough to use. Just run autolog.exe, fill in the dialog, and hit Enable. To turn off auto-logon, hit Disable. If the DefaultPassword is NULL, autologon will only occur once and then be disabled. Also, if the shift key is held down before the system performs an autologon, the autologon will be disabled for that logon. You can also pass the username, domain and password as command-line arguments: autologon user domain password
