Windows lets you know when your computer’s Internet connection is limited or absent entirely. What is this sorcery?

It’s quite annoying when this does not work properly, it’s also annoying that windows will choose a non-routable Ethernet connection over a routable cellular connection unless you change some registry keys to force it to use the cellular. This behavior changed suddenly during an update and has stuck around. Our companies entire fleet of industrial computers running windows 10 with cellular modems connected by Ethernet to monitoring devices went offline and we had to touch each at distance sites to force them to use the cell connection.
I’ve run into that one as well. Very annoying. For me it was just one PC, but it triggered at a really bad time where I had an expensive consultant sitting next to me waiting for the system to properly function again. I think I re worked everything to use serial instead of ethernet. I wasn’t aware of a registry hack.
If you need to force windows to use a cellular connection the below reg entry should work. By Microsoft’s own stated logic this should not be necessary as it would do the test Thom’s link mentions but they hard coded this behavior for some reason. Windows will also ignore interface metrics so you have to do this change if you want cell to work when limited Ethernet is connected.
