>Windows 10 upgrade prompt changed so if you closed the box you got the upgrade. For people having spent some time closing the box to refuse the upgrade this cannot have been anything but annoying.

My procedure for installing windowses for the last ten years (on my box)

1) unplug the network cable
2) install
3) disable updates, windows firewall
4) plug the network cable.

For the next time, it would also involve copying the hosts file from the old one. It's a few dozen lines long.
