I had this issue on my old laptop, and it seems to have reappeared on my new one. Running windows version 1709.
I've used the mobile hotspot feature occasionally (and it works as expected).
SSID: Hotspot
Password: thisIsAHotspot
However, when I turn off mobile hotspot, there's often still a network being broadcast from my laptop something along the lines of "DIRECT-product_name". I can't log in to it using thisIsAHotspot.
It exists as "Local Area Connection* 13" in the network connections view and is called "Microsoft Wi-Fi Direct Virtual Adapter". If I disable it, the network goes away, but then I have to go into device manager to re-enable it every time I want to use my hotspot.
How do I get it to quit broadcasting a network address when I'm not using it?
