Allows UPnP devices to be hosted on this computer. If this service is stopped, any hosted UPnP devices will stop functioning and no additional hosted devices can be added. If this service is disabled, any services that explicitly depend on it will fail to start. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\System Services!UPnP Device Host (2) REG: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\upnphost!Start
