Windows Does Not Require You to Press CTRL+ALT+Delete to Logon

After you click to select the Require users to press Ctrl-Alt-Delete before logging on check box on the Advanced tab of the Users and Passwords tool, the computer may start without requiring you to press CTRL+ALT+Delete to log on.

This issue can occur if your computer does not belong to a Windows NT domain and you use only one default user account on your computer.

To resolve this issue, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.
2. Double-click Users and Passwords.
3. Click to select the Users must enter a user name and password to use this computer check box.

If your computer is not a member of a domain, Windows starts using either the default Administrator account, or an account you created during installation without prompting you for a user name and password.
