Windows Update Error 0x80070643 When Installing KB5034441

I have multiple computers, that fail to install the Windows Update KB5034441.

As so often, Microsoft have done a brilliant job of not fixing the problem for four months as of this writing. Well done! 😏

After reading up on the web, it seems that the error is related to an update to the Windows Recovery Environment (WinRE).

Surprisingly enough, I have the problem only on computers that do not run WinRE at all. Those that do have no problem. Now the web only has solutions (some of doubtful quality) for computers that do run WinRE, so they are not applicable to my case.

Here is my approach to this:

First of all, verify that you are not running WinRE: in an elevated command prompt run "reagentc /info".


If you get a similar output, saying "Disabled", then you can follow this advice. Otherwise, go back to the web, and good luck to you!

After having verified that this update is not relevant for me, I decided to hide it:

  • Download the Microsoft Show or Hide Updates Tool from here
  • Run the tool
  • click "Advanced"
  • uncheck "Apply repairs automatically"
  • click "Next"
  • be patient ...
  • click "Hide updates"
  • check KB5034441
  • click "Next"
  • let the tool do its job

Now you will not see the failed (and failing) update any longer.

Should Microsoft ever choose to fix the update, you can unhide it using the same tool and install it.

Ah, beautiful silence in the Windows Updater now. 😁
