I have an Asus NIC. It is used for one, and only one thing, playing videos connected to a projector. In case any of the files contains some malware, it will be restricted to that box, and since it is never online, it shouldn't be able to send or receive anything. It is my way of protecting my other computers. Well, guess what, today I found the update to Windows 10 icon on it. My router doesn't broadcast its SSID and the NIC has never been connected to it. I can't use it in Airplane Mode since a Bluetooth mouse is connected as my "remote control". How Microsoft got that thing on there is actually a bit frightening. Twitter is to communications as haiku is to literature.
