Remove hidden network adapter

Description

After editing IP details and attempting to apply the changes, Windows complains that the IP address is assigned to a previously removed network adapter.

Workaround

Click 'no' on the warning dialog.

The dialog wording is confused by Microsoft's choice of double negative.

Resolution

1. To remove the missing card from the registry
2. Open a cmd prompt (run as admin in later Windows versions)
3. Enter
   set devmgr_show_nonpresent_devices=1
   start devmgmt.msc
   
4. Select show hidden devices from the view menu
5. Expand network adapters in the device tree
6. Select the greyed out interface
7. Right click and select uninstall

A reboot may be required to force services to rebind to the correct adapter
