Windows update (KB5034441) Error (0x80070643)

Yes, in my opinion, they (Microsoft) are NOT going to offer some Automatic Update or one-touch easy fix. This one you are going to have to fix it yourself, or just ignore the update as it really has no effect on operation for 98% of PC's.

If you read the pages of this post, you will find there are several Essential Steps needed to correct the issue. Two of those are Resizing your Recovery Partition and manually pointing (directing) Microsoft Windows 10 to the correct Recovery area (on your Boot Drive C: inside the Windows Program first, or moved to a sized Recovery Partition. Sometimes you need to find (get) the essential files that are part of the Recovery. Without these files the Update will NEVER complete.

Some of the directions located from Page 38 to 44 also give a solution that is a complete replacement of Windows 10 Operating System by downloading the proper Windows 10 OS on a Thumb Drive and installing Windows 10 again (saving your programs and data without loss). This is the method I would recommend, especially if you are not familiar with Recovery Partitions, reagentc, and Command Com working. Making Windows find the needed Recovery Files is tricky.

Read the pages from this post, you might need some help in completing the steps needed, but some are easy.

Unless, of course, they are trying to upgrade to Windows 11.

One should not need to take on the role of an IT professional to resolve this.

Disappointing.

There is a known problem with that update.

Fixing the KB5034441 Update Error

I wish to share my experience of fixing this error from all the resources I found

As you can see we have an error updating KB5034441. I have Found a solution and glad to explain.

We have a health Recovery partition , it's just not big enough.

Opened A Command Prompt with Administrative Privileges.

type cmd in the search bar and right click Command Prompt and select Run as Administrator.

This next command is the most important for without it one must go through much added procedures to get a successful ReAgentC/Enable run.

* Run ReAgentC  /Disable   This is done to move the REimage to system directory for later use

Run    DiskPartA program for performing tasks on the hardrive

Run   list disk   Please take note of the type of disk you have .ie. An asterisk under * GPT

Run   Sel Disk 0         The Main Disk or the one with the Windows OS on it C:\ most likely       

Run     Sel Part 3         The Primary Partition. we're going to shrink this to add to part 4

Run   shrink desired=300 minimum=300   this will give us plenty after we make a new partition

now Select the Recovery partition

Run     sel par 4   This is the Recovery Partition we’re going to delete then create new

Run  detail par   Let’s get details about the Recovery partition for comparison later if needed.  

you should see an asterisk next to the recovery partition as it is the one selected.

Run   delete Part Override

now, we're going to create our new larger partition.

For GPT Disks :

Run   create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac

**** Run   gpt attributes =0x8000000000000001

Run   format quick fs=ntfs label=”WindowsRE”

If your disk is MBR, :

run create partition primary id=27

run  set id=27

Run   List par Let's see how big the partition has become

Your Recovery partition size may very. it should be > 800

run Exit to exit out of Diskpart. and return to the Command Prompt.

Run     ReAgentC  /Enable to enable the Recovery partition

this is when the REimage is now going to be place back on the recovery partition

If enabling was successful, and it should be, exit out and close all windows and check for updates and it should work as it did for me.

If you receive an error that the REimage was not found then please comment and I have solution for that as well. I will post.

I've posted this earlier but you do not have to mess with resizing partitions to fix this error. Just follow the tutorial below.

How to Do a Repair Install of Windows 10 with an In-place Upgrade

The above worked for me last month - no more pesky update error message, after many months. Check the box for Download updates, drivers and optional features (recommended) box when it gets to that point. Otherwise, follow the tutorial step-by-step.
