Windows update (KB5034441) Error (0x80070643)

Yes that is the known problem.

When I tried to install the windows update "2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441)" I received the error code (0x80070643).

I have already tried, restarting my computer, waiting a bit before retrying, running a memory diagnostic check, checking all my drivers for updates, installing optional updates, and running a malware scan.

When I tried to run the windows update troubleshooter it said "diagnosing problems" but never fixed them and I was still unable to install the update after running the trouble shooter.

Any help would be appreciated.

There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)

Here is what you need to know ...

For everyone who is failing at this tutorial

This tutorial only works if your Recovery partition is your last partition. If it isn't last, it won't work because of the below rule:

With DiskPart, you can extend a partition only when the location of the unallocated space is right behind it.

Fiddling with this tutorial otherwise will result in 250MB of unallocated space, see below (Disk Management)

But, sadly, even if the recovery partition is the last partition, and even if you successfully increase the size of the recovery partition (in my case, to just under 1Gb), the Windows update can still fail. As many people have discovered, there is obviously some other magic ingredient that is required in order for the Windows update to be successful - increased recovery partition size is not the sole requirement.
