It's an optional update. It doesn't automatically install without activating the option to do so.

Even registry changes won't stop their stomping. My final straw was changing the drivers for AMD for the fifth time, despite editing the registry, sending console commands, and exiting settings. MS drivers just bulldozed right over them. I said fuck it, set up another ssd with Bazzite, dual booted, and three months ago converted the Windows drive to a VFAT, after not booting Windows for a full year. I miss Fusion 360, that is all. I do not miss the headaches. Linux took time to setup, time to learn, and time to personalize. I still think it saved me time overall with how few problems arise, however.

You can pause Windows updates, although I'm not sure I would suggest it because they are usually patching a baotlad of security vulns.

Not defending Microsoft in any way, just pointing out that the option exists. Of course you will get updates once it unpauses, but maybe another CU down the line won't break shit.
