How to make Wi-Fi Sense safe
If you don't want someone automatically logged in to your Wi-Fi, there are a few options. The best option is to turn Wi-Fi Sense off from the beginning.
When you first install Windows 10, choose the "Custom" install so it takes you through all the setup options. Turn off anything related to sharing your information or logging into Wi-Fi networks automatically.
If you jumped over these options during install, you can turn off Wi-Fi Sense later. In Windows 10, click the Start button and choose Settings to go to the new Settings screen.
Go to Network & Internet >> Wi-Fi >> Manage Wi-Fi Settings (only available on computers that support Wi-Fi). Turn off "Connect to suggested open hotspots," "Connect to networks shared by my contacts," and uncheck all the options under "For networks I select, share them with my contacts."
Of course, you don't have to turn off Wi-Fi Sense completely. If you still want to use it but want more control, here are some simple ways to customize how it works.
To start, you can remove people from your Outlook, Skype or Facebook contacts. However, if you actually need to contact them, then that's not always practical.
Your next best option is to not share all your Wi-Fi networks. The first time you log into a Wi-Fi network with Windows 10, it will ask if you want to share it with others. Simply say no and it won't be shared.
If you want to go the other direction and be really sure that Wi-Fi Sense stays completely away from your network, you can change your network name in your router to include "_optout" (minus the quotes) at the end. So, if your network name was "my network," you would make it "my network_optout." Learn how to change your network name, and pick a good one.
