Windows update (KB5034441) Error (0x80070643)

Last night, I saw that there was an update. I ran it, and this time it appears to have successfully completed without issues.

I have not followed any of the steps in these 48 pages of troubleshooting, so something must have been addressed.

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 DiskPart A 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.

Is Microsoft going to pay me to fly or drive to 4 states to get hands on the problematic computers in the businesses where they are affected so that "easy" fix can be implemented? No? Then your remark is entirely unhelpful.

Not everyone affected here is a computer is using in their own home.

There is a known problem with that update.

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.

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.
