This policy setting turns on or turns off an HTTPS listener created for backward compatibility purposes in the Windows Remote Management (WinRM) service. If you enable this policy setting the HTTPS listener always appears. If you disable or do not configure this policy setting the HTTPS listener never appears. When certain port 443 listeners are migrated to WinRM 2. 0 the listener port number changes to 5986. A listener might be automatically created on port 443 to ensure backward compatibility.
