Same SSID and password?
... or a friend's computer with Windows 10 has logged into the router at the flat and the password has been automatically shared with your son's computer? Doesn't need to be Windows 10, apparently.
Obviously, Microsoft have to store the passwords on their servers and I would imagine that the NSA will have a copy. Location data, SSID and bang, they're in. Enable remote management on the router, install hacked firmware and they can watch everything that happens via that router.
