All the router options I read about as well as software options all talk about "internet" use. My son almost never goes on the internet. He plays a game that he downloaded from the internet but is now just an icon on his PC. I want a device, router, or software program, basically anything that can shut his computer off entirely at 9pm. I don't want him to be able to use the computer AT ALL after 9pm on school nights. And I need it to shut off only his PC and not mine. We both have Windows 10. Please is there anything out there?
