Concerns about new feature in Windows 10. 's Wi-Fi Sense 
This is the ability to share the Wi-Fi network password between computers with the Windows 10 operating system. The Wi-Fi Sense function that will be integrated into the new Windows will allow users to share their connection to a Wi-Fi hotspot with their friends. To do this, it will be enough to select the corresponding field in the menu and when someone connects to a wireless network with a Windows 10 device , they will have the option to share the connection password with their contacts on Facebook , Outlook or Skype . Microsoft aimed to make it easy for users who recognize each other to access the same wireless network, but such a feature may pose risks of facilitating malicious elements for intercepting passwords.
If you don't want to have the feature enabled, you can simply uncheck it and give the password manually to whoever you want. You can also add the name of your network "_optout".
The giant company notes, however, that the Wi-Fi Sense in the new Windowsdoes not provide access to the files of other devices, but only to the web through the network.
