Beware of wifi sense: Windows 10 security alert as new 'feature' automatically shares your wifi passwords with ALL Outlook, Skype and Facebook contacts who also have the software. Please untick: Outlook.com contacts Skype contacts Facebook friends and turn off: Connect to networks shared by my contacts Connect to suggested open hotspots But worse case: I hate this part: Sign in with your Microsoft account to use Wi-Fi Sense (I don't use Microsoft account)
I don't think it will work the way you describe!! Fact is, if you connect to WiFi, the related password is checked online every single time with either your Modem and/or the WiFi Provider you use mobile! And any of those WiFi Password are stored on your computer you use to connect! Don't start to blame Microsoft for something which is done from Day 1 of WiFi avaibility! The use of WiFi Sense is simply shorten your access time to the Microsoft Apps like Skype etc. and will just use any of the available WiFi Hotspots your computer could access and has the password for, if you're not connected by Ethernet Cable! Don't be paranoid!!
