You can configure automatic logon using the registry, but typing AUTOLOG.EXE is much easier:
1. Fill in the dialog.
2. Press Enable.
NOTE: To disable automatic logon, run AUTOLOG.EXE and press Disable.
NOTE: If DefaultPassword is NULL, automatic logon will only occur once.
NOTE: If the SHIFT key is held down before automatic logon begins, it will be temporarily disabled.
