Wi-Fi Sense in Windows 10 manages your wireless connection by automatically connecting to open Wi-Fi networks and the password protected networks (Private) which your friends have already been connected to. In other words, Wi-Fi Sense is kind of a Wi-Fi password sharing feature in Windows 10. To turn off and disable Wi-Fi Sense in Windows 10, do as follows:
1. Open the Setting from the Start Menu
2. Go to the Network & Internet settings
3. Make sure to click the Wi-Fi option from the left pane, so on the right side of the screen available Wi-Fi networks will be shown.
4. Scroll the list of wireless networks down, and click the Manage Wi-Fi Settings optin
5. Now, under the Wi-Fi Sense settings, there are 2 toggle buttons to switch On/Off: Connect to Suggested Open Hotspots and Connect to Networks Share by My Contacts.
6. If you don't want your friends (Contacts in your Outlook.com, Skype, and Facebook accounts) to automatically connect to your private wireless network, then make sure to toggle off the latter option to turn off the Password Sharing feature.
