Yeah, I feel with you :). Took me some days to figure this out thanks to the info here in the forum. Don’t know why the Chinese can not put the drivers up for free and easy download, they send these boxes around the world. Baidu is a complete nitemare.
Anyways, the F5 works now as supposed to. I got rid of the Home version and replaced it with Win 10 LTSC, the version MS does not want us to use. Lean and clean, no bloat and spyware disabled. No Edge, no Store, no Apps, no garbage. Way to go.
