Default Behavior

UPnP Device Host is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the UPnP Device Host service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If UPnP Device Host fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the upnphost service has failed to start due to the error.

Dependencies

UPnP Device Host cannot be started under any conditions, if the following services are disabled, deleted or working improperly:

Restore Default Startup Configuration for UPnP Device Host

Before you begin doing this, make sure that all the services on which UPnP Device Host depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config upnphost start= demand

3. Close the command window and restart the computer.

The upnphost service is using the upnphost.dll file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
