windows update error (0x80070643) for kb5001716

That is correct. "KB5001716, 2024-03" was installed correctly and now the same update is trying to install again and is giving me an error message.

Exactly the same issue started to happen several hours ago. I did first two options you've recommended but that didn't help. Don't want to perform a repair-upgrade though. There is definitely something wrong with this KB5001716.

P.S.

* First, there was an update which installed correctly, it's listed in Windows Update Log as "KB5001716, 2024-03"

* Immediately after that, when I checked for updates again, there is another KB5001716 which fails to install.

* Now, my Windows Update Log contains another failed entry for the same KB - "KB5001716, 2023-10" at the top (note that it has older date), with error code 0x80070643

You are so right. I directly saw the same problem in the Netherlands. The first update 2024-03 goes well, the second directly after with 2023-10 fails. This is an error at Microsoft. So let Microsoft fix the problem, and don't let people struggling with downloading tools etc.

I used the hide update tool from microsoft to get rid of this problem.

Windows Show/Hide Update Tool Unavailable.

Why doesn't Microsoft release this?

What else is hidden in the code?
