Description
Allowing a system to automatically log on when the machine is booted could give access to any unauthorized individual who restarts the computer. Automatic logon with administrator privileges would give full access to an unauthorized individual. If this setting was enabled at any point, a password may also be present in the registry, and must be removed.
