A lot has been made recently over the feature that allows Windows 10 users to share their Wi-Fi settings with other Windows 10 computers. Essentially, Wi-Fi Sense shares stored credential information and allows friends and family to logon to encrypted Wi-Fi networks without having to know a password or specific network information.
This sounds like both a very useful feature and one that could be potentially dangerous. But, Microsoft has developed specific stipulations about how Wi-Fi Sense works:
Does not show the Wi-Fi password
Allows full customization, including disabling it completely
Shared credential information is only available to valid personal contacts from Outlook, Outlook.com/Hotmail, Skype or Facebook
Only available to others running Windows 10 with Wi-Fi Sense enabled
To customize how Wi-Fi Sense works follow the gallery above, which takes you to All Settings > Network & Internet > Wi-Fi > Manage Wi-Fi Settings.
