Default Behavior
UPnP Device Host is a Win32 service. In Windows 8 it will not be started until the user starts it. When the UPnP Device Host service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If UPnP Device Host fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the upnphost service hasn't been started.
