Windows 10 22h2 security update [KB5034441] fails to install with code: 0x80070643

I agree and this needs to be repeated.

I am running Windows Home on my laptop and do not have BitLocker.

(I don't even use BitLocker on my Pro desktop.)

@Gary_Ulrich1 -- just "hide" the specific update, and move on.

The next time that you run Windows Update, it will find any brand-new updates (such as the daily update to Microsoft Security Essentials) and will try to apply all the newly-released updates .

The only down-side is that your computer will still be vulnerable to the WINRE-related issue that the failed update is intended to fix. I do not know if there is any exploit "in the wild" that will leverage the security-issue. Nor do I know if your computer will be a target of the exploit. Just accept this "risk".

What in the world? Most people who have Windows computers won't know half of what is being discussed on this board, much less how to apply any of it. MSFT has made the world of computing an absolute b*tch. My Windows 10 computers have been running great up until the last few months. More and more issues with updates and other glitches have started to pop up. I think this is MSFT's way of forcing users to throw their hands up and just move to the next version of Windows. I've seen it play out like this since Windows 95.

@IbrahimKonuk ---

This is a brand new update.

Yes, new for the January 2024 Windows Update.

Is this a known issue?

Yes, judging by the number of posts to this discussion thread, and by various web-sites that are reporting the issue -- just do a Google/Bing search for KB5034441 to find those reports.

Is there a resolution specific to this update?

Yes.

You, and several others need to read through all the posts within this discussion thread, to find useful information.

Since MiniTool does not work when the WINRE partition is first on the disk-drive,

download an older (but free) version of Macrium Reflect from www.MajorGeeks.com

Admit that your current disk-drive is old, and probably out-of-warranty, and buy a new SSD, and connect it.

As you start-up Macrium Reflect, you should choose to resize each of the partitions that you want to copy, e.g., increase the size of the WINRE partition, and decrease the size of the "C:" partition, and then launch the copy operation.

As you configure it, you may first need to configure to "shrink" the C:, and then configure to "expand" the WINRE partition. This avoids M.R. complaining that there is not room for the C: partition, due to the increased size of the WINRE partition.

When the copy completes, power-off the computer. Disconnect and physically remote the current disk-drive. Restart into BIOS SETUP mode, and configure it to boot from the SSD. Restart Windows, and rerun Windows Update. Keep your current disk-drive as an "archive" of your system, as it was in early January 2024.

I am very reluctant to use software like Partition Magic to "shrink-in-place" the "C:" partition before "sliding" it over by a few GB to create free-space before it.

If that "slide" gets interrupted, you might have really messed-up the partitioni.

I would rather deploy a brand-new disk-drive, to avoid mangling the current disk-drive.
