You have to run it again after every major update.

Run the debloater every update. Some stuff in there is actual settings, but other stuff will be "repaired" by windows.

Also, a workaround to that screen (so far, at least) is to shut the computer down and start up again and it doesn't return till next update.

Question: if you already don't like Windows, I assume you don't care about the new features that come with new updates. So I wonder - why do you update at all? Set everything up as you want it, remove all the hot garbage as you see fit, and disable updates.

Give them a break. They just moved from Windows, you just need to relearn to breath after that. Moving to another distro is a small step in comparison.
