Windows NICs cleanup

This tip comes handy in case you're working with your NICs, adapters and bridges, and you're stuck with some unremovable ones.
First of all, and for the sake of safety and recoverability, create a Windows Restore Point.

From the help displayed from netchg /?;

... netcfg -d
    Example:
    netcfg -d
        Performs a cleanup on all networking devices.
        This will require a reboot."

From an elevated command prompt, run the netcfg /d command, then reboot the machine.
If everything will be OK you'll find only the correct adapters.
