Windows 10 Shares Your Wi-Fi With Contacts

Kill Wi-Fi sharing
By default, Windows 10 is set up to share your Internet connection over Wi-Fi. This is a nifty feature if you want it, and a dangerous one if you don’t. To be on the safe side, you should probably just disable it right from the get-go.
Open the Settings app from the taskbar or Start Menu, then open Change Wi-Fi settings and click Manage Wi-Fi settings. Now, uncheck all the boxes under “For networks I select, share them with.”
You may also want to slide the toggles to off underneath “Connect to suggested open hotspots” and “Connect to networks shared by my contacts.”
