I have just upgraded to Windows 10 from 8.1. It went very smoothly but when I tried to go to the WiFi tab in SETTINGS/ NETWORK AND INTERNET (so I can turn WiFi Sense off) it isn't there. It's missing. I'm online with no problem but I can't access the WiFi tab. Any help would be greatly appreciated. My PC is custom built with 12 gigs of ram, and a blisteringly fast internet speed.
