Ok, done that. Did several tries and took several screenshots. The things shown on device manager change as my phone connects and disconnects a few times, and then it shows something different after after my phone boots itself.
First it shows only the 5 newly installed things from the XP drivers, then MT67xx preloader appears, then CDC Serial and LGE Android Phone appear instead, and finally after my phone starts booting it then shows LG K8 4G.
The 5 drivers (under Ports in device manager) were all that I installed, nothing else.
