Wow. Thanks for that, but I'm annoyed with a thing in Windows Update. (This issue is not related to Cumulative Updates, but it is related to Updates.)

I had turned on the Active Hours feature in Update & Security. But I always have to click Check for Updates once every day so that Windows can install the Defender Updates, like the Security Intelligence Updates. It can't install it automatically. What can I do? I had update install errors many months ago and solved it using the built-in wsreset.exe app. But now, it's the problem of Defender updates. It scans automatically and tells me that I'm up-to-date, but when I click that Check for Updates, it shows Updates available.

It's easy to ride down a hill while it's hard to climb the hill back up. Like that, it's easy to malfunction a computer while it's hard to fix it.

The previous update I made (forced to) a couple of days ago, broke my work computer, I've been trying for the past couple of days to make software that I use daily just launch, Blender for instance is just a zombie app on my computer, whenever I run it, it just hangs there in limbo, even end task in task manager doesn't work anymore, everything is extremely slow, I spent 3 minutes looking at the screen, copying a 504 KB file from a folder to another on the same drive!

This broken updates nonsense is been going on for a very long time, and it's wasting millions of people's time and causing damage and losses. Enough, stop forcing broken updates, do your jobs and test before you go around breaking people's computers.

As I type into the search bar, the Search box opens up black with no search response. Worked perfectly before this update was installed. Uninstall this update and only this kb and search working correctly and perfectly immediately with no other changes whatsoever.
