You can control Automatic Updates and/or disable them but you probably never bothered to read the screen on the Windows Settings because it’s too complicated for you. Did you know that you never have to pay for an upgrade if you have to a Windows 7 licence, now unsupported for three years because it was released in 2010 and obsolete within 5 years but still supported & updated until 2020? The only reason my desktop is still running Windows 10 is because at < $100 it was obsolete when I bought it but used my Windows 8 licence. Windows 11 doesn’t support my hardware. MS policy since XP has been to support each new release for ten years for ten years from release date. That means by the time Windows 12 is my only MS-supported option, I can use the same deskto I acquire next, either built myself or bought as a prebuilt “Barebones” (no OS at all) either locally in Toronto or online.
I use a Mac.
I do have Parallels and Win7 on it for running one expensive CAD program not available in a Mac version.
