You can't disable auto updates in 11. You can only pause them for up to a week. As I only use my PC for sim racing, I don't leave it on any other time, so all in all, I find it's just easier to let Microsoft have its way.
EDIT: I know you're a PC-man, so you're probably just shaking your head at me. 😖🤪
It seems there are ways to disable it via the 'Local Group Policy Editor', but I'm not sure I'll bother. I'll just go back to my nice Mac Studio instead and put up with the occasional Windows-induced headaches which only happen when I use my sim setup and have to endure the evil that is Windows. 🥹
