It's true that you can't turn disable software updates without a registry edit, but those updates are purely security patches and nothing else. Although I do believe on principle that users should always be able to control updates, there's really not a lot to complain about here. (And you can control the updates, with a registry edit.)

There is? Not in mine.
I just double checked, I'm running Windows 11 IoT Enterprise LTSC 2024, which appears to still be the latest.
