There's only been a few really bad ones, but Microsoft botch Windows updates quite regularly.
OK, please show us the proof then. If it's as regularly indeed like you claim then it must be documented somewhere as a greppable list.
Tech blogs would have a field day getting traffic on their site by keeping track and documenting on such regular mistakes if they exist.
"In general, I apply Windows Defender updates as soon as they’re available. Why? Microsoft hasn’t screwed up any of them too badly. You’re better off applying those updates than letting them slide for a week or two."
It's the other Windows Updates that they botch frequently enough to make people wary of patching immediately.

My own anecdote: When I got my M3 Pro in April and had to start afresh, it was stuck in a restart loop and had to take it to the Genius Bar; they asked me to answer ‘no’ to some question that I was answering differently. That was it. I have no idea on the root cause or why it was fixed this way. I don’t remember the exact screen where the answer was supposed to be different.
