Fix: How to remove hidden or phantom interfaces from Windows

Leave a comment

Sometime you will note that some network interfaces would either not work or just give errors. This usually occurs when using images on HyperV but just in case you need to remove hidden or phantom devices like ‘network adapter #5’, here’s how.

:: Open command prompt
:: Type CMD
:: Type set devmgr_show_nonpresent_devices=1
:: From the same window (Do not close the window in this process), type devmgmt.msc

This will load the Device Manager. Now, click on ‘View’ and select ‘Show hidden devices’.

Now you can simply either delete the hidden/phantom interfaces or uninstall the device.
