Windows 10 Shares Your Wi-Fi With Contacts
Starting today, Microsoft is offering most Windows 7 and Windows 8 users a free upgrade to the software giant's latest operating system - Windows 10. But there's a very important security caveat that users should know about before transitioning to the new OS: unless you opt out, Windows 10 will by default share your Wi-Fi network password with any contacts you may have listed in Outlook and Skype — and, with an opt-in, your Facebook friends.
This brilliant new feature, which Microsoft has dubbed Wi-Fi Sense, doesn't share your WiFi network password per se - it shares an encrypted version of that password. But it does allow anyone in your Skype or Outlook or Hotmail contacts lists to waltz onto your Wi-Fi network - should they ever wander within range of it or visit your home (or hop onto it secretly from hundreds of yards away with a good 'ole cantenna!).
