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.

Dependencies

UPnP Device Host can't start, if any service from the list below is disabled or not available:

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 corrupted or deleted, you can put it back in there.
