I have just installed on my desktop PC the "Feature update to Windows 10, version 1607" that Microsoft pushed on me. Now when I click the icon on the task bar to display the list of networks, at the bottom of that list an "Airplane mode" button appears. This invites me to turn airplane mode on or off. This is really stupid, because this is a DESKTOP computer. This doesn't seem to affect use of the computer, beyond being an annoyance--but is this what Microsoft considers to be normal operation? Thank you.
