Windows can be configured to automatically sign the user back in after a Windows Update restart. Some protections are in place to help ensure this is done in a secure fashion; however, disabling this will prevent the caching of credentials for this purpose and also ensure the user is aware of the restart.
Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Windows Logon Options >> "Sign-in last interactive user automatically after a system-initiated restart" to "Disabled".
Verify the registry value below. If it does not exist or is not configured as specified, this is a finding.
