Open Control Panel, Device Manager, Other Devices. Is there anything listed there? If there is, the option to uninstall or disable is present. I see one such device in Other Devices but it doesn't appear in the WMP list that you show. The only thing it shows is a USB port 5. I have 8 and don't know what's on that port. It also doesn't show up on my network devices. Whatever you have, it seems to be in your Network Devices.
Just tossing out some observations.
