A device driver failed to install (incompatible), and left an orphan network connection which I cannot find a way to remove. Apparently it's in use so it cannot be deleted.
Is there a way to force delete it? I have tried locating it via registry, but I couldn't find it, also tried doing it via merge or delete network locations, but since its in use, it cannot be removed.
Tried this?

You might also want to try booting into Safe Mode to remove the misbehaving connection.
Yeah, those didn't work.
Managed to find the culprit: Virtual box. Uninstalled it and all my network adapters, and re-installed Ethernet drivers.
Problem solved. It was strange, as it wasn't showing up as a proper adapter neither..
