Wifi-Sense is a windows 10 feature that will make your wifi password (nearly) public. It will not only be given to friends, but also friends of friends and there's no way to turn it off. If there is a single windows 10 user within your network, microsoft will have your pass.
The only thing you can actually do is add "_optout" at the and of the SSID. How far have we come that they can basically dictate how we have to name our networks? Well, microsoft isn't the first company to do so, you had to add "_nomap" to stop google from mapping your wifi before...
