| Automatic logon must be disabled. When automatic logons are enabled, the default user account is automatically logged on at boot time without prompting the user for a password. Even if the screen is later locked, a malicious user would be able to reboot the computer and find it already logged in. Disabling automatic logons mitigates this risk. |
