Wi-Fi Sense feature in Windows 10 automatically connects you to Wi-Fi around you to help you save your cellular data and give you more Internet connectivity options. It also let you exchange Wi-Fi network access with your Facebook friends, Outlook.com contacts, or Skype contacts to give and get Internet access without seeing each other’s Wi-Fi network passwords.
With the Windows 10 Build 14342 released today, Microsoft is removing this feature due to low usage.
We have removed the Wi-Fi Sense feature that allows you to share Wi-Fi networks with your contacts and to be automatically connected to networks shared by your contacts. The cost of updating the code to keep this feature working combined with low usage and low demand made this not worth further investment.
Wi-Fi Sense feature that will get you connected to open Wi-Fi hotspots that it knows about through crowdsourcing will continue to be available in Windows 10.
