Discussion

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.
