Remove hidden network card from VM on Hyper-V

Recently, I add a new SATA disk to my PC for locating the hyper-v VM. When I export and import VM to this new disk and boot it, the network card is added to this system again and the static IP cannot be set as the original value. The warning message show up then.

By searching Goolge and finding out some solution, I decide to try it by myself.
At first, open "command prompt" by "Run as administrator" right.
( It is a important step that it will fail if you lose this.!)

Follow the screen command to execute it for opening Device Manager.

Select "Show hidden devices"

You will see the hidden network card on the system now.

Select the first hidden network card next to click "Uninstall" button

Repeat the above activity on the second network card.

After finishing this, it will only keep the present network card on system.

Remind you to reboot the system right now so that the change process will be effective.

Now you can set the original IP and no show any warning message again!
