Fix: Teredo Tunneling Pseudo-Interface Error Code 10

Imagine going through your device manager and finding a yellow exclamation mark right next to Teredo Tunneling Pseudo-Interface. And when you click on the device, it displays the error: “The device cannot start (Code 10)”. If this has actually happened to you, then there’s no need to fret.
