Clearly Windows 10 spies on you any time you use the System Settings. Then, I flushed the Windows DNS cache and went back to the System Settings. Kicking more tires in System SettingsAll the DNS requests above resolved to the zero IP address, except for sub-domain ecn.dev.virtualearth.net. There was an outbound request made to port 443 at 23.78.209.31 which is the IP address of the virtualearth domain. DNS on Windows 10 is more complicated that it used to be with earlier versions of Windows.
