In the latest releases of Win 10 Home, at least once you have connected to the network, that button does not exist. They prompt you to enter your WiFi info first, then ask you to log in. And once you have entered the WiFi info you cannot get back to that screen and remove it until after you have set everything up. At least not without a factory reset, which I didn't actually try.

They force you to log in with a MS account during the initial setup then once you are in you can add a local admin account. Then you can log into it and remove the MS account. Its absolutely horrible.

I have been dealing with this a lot lately, had several laptops that were Home and could not get in to them without the MS account. Its a huge pain.
