Fix Recommendation

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "MSS: (AutoAdminLogon) Enable Automatic Logon (not recommended)" to "Disabled".

Ensure no passwords are stored in the "DefaultPassword" registry value noted below:

Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \Software\Microsoft\Windows NT\CurrentVersion\Winlogon\

Value Name: DefaultPassword

(See "Updating the Windows Security Options File" in the STIG Overview document if MSS settings are not visible in the system's policy tools.)

Severity Override Guidance: If the DefaultName or DefaultDomainName in the same registry path contain an administrator account name and the DefaultPassword contains a value, this is a CAT I finding.
