AFAIK, the Microsoft Virtual WiFi Miniport Adapter is a virtual adaptor for sharing your internet connection (ie. making a wifi hotspot, or 'hosted network').
To disable this, open an elevated command prompt (cmd as admin) and type in the following commands, in order:
netsh wlan stop hostednetwork
This stops the hosted network
netsh wlan set hostednetwork mode=disallow
This disables the hotspot.
This worked for me and removed the adaptor on my computer.
