How to disable Windows 10's Wi-Fi Sense password sharing
As convenient as Wi-Fi Sense is, however, not everyone's thrilled with it. Windows 10 enables Wi-Fi Sense by default, but you can disable it. Here's how.
How to disable Wi-Fi Sense in Windows 10
First, open the Start menu and head to Settings > Network & Internet > Wi-Fi > Manage Wi-Fi settings. In here, you basically want to disable every option you see, as well as tell Windows 10 to forget any Wi-Fi networks you've signed into in the past.
That's easy, and all well and good. But what if you don't want your friends sharing the information about your network's password with their friends That takes some additional tinkering, and it's not obvious. There isn't a mere option toggle in Windows 10 itself.
Instead, you need to dive into your actual router's settings and give your network a new name with "_optout" at the end. For example, a network called "WiFiSenseUgh_optout" wouldn't be stored by Wi-Fi Sense, while one that's just called "WiFiSenseUgh" would be usable with Microsoft's sharing feature.
Yeah, it's a pain, but if you don't add "_optout" to your network and want to stay out of Microsoft's Wi-Fi Sense database, you'll need to manually enter your password on your friends' devices when they pop by your house and make sure to uncheck Windows 10's "Share network with my contacts" box when you do so.
