Keep getting 0x80070643 Windows Update error

[W10PowerUser]

My computer keeps giving me 0x80070643 error when i try to update it. I have ran the troubleshooter and didn’t help. Don’t know what to do next

There is a known problem with the KB5034441 update. It’s better to pause updates until a solution comes out.

Just block/hide the update by using the WUShowHide.diagcab tool from Microsoft: https://download.microsoft.com/down...9cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

You can also resize the Recovery partition to 750 MB or more. This already lets you install the KB5034441 update.

I also put my automatic update on pause. In theory, they said they are working on this but it’s taking way too long. The pause is set to expire on 6/5/2024 so I hope they fix it before then.

Yeah, I also installed Update KB5034441 after I used a third party partition manager to upsize the Recovery Partition. However, this changed its ID and attributes. I do not see the Recovery Partition listed any longer. Now my 100 MB EFI System Partition is listed in Disk Management as separated from Boot Drive C and given drive letter Z in File Explorer.

No need to temporarily unhide the recovery partition. This is what works:

Download Windows 22H2 from the Microsoft website. You can create an ISO or a USB with the media creation tool. If you use an ISO you will have to mount it virtually.

Find the install.ESD file Convert it to install.WIM following these steps:

Create a directory for the install.ESD and copy the file you located above.
From that directory, enter:
Check the status of recovery
reagentc /info
Disable windows recovery
reagentc /disable
dism /Get-WimInfo /WimFile:install.esd
dism /export-image /SourceImageFile:install.esd /SourceIndex:1 /DestinationImageFile:install.wim /Compress:max /CheckIntegrity
Open the install.wim with 7zip (or peazip) and locate folder winre.wim (including reagent.xml
copy the contents of the folder into C:\Windows\System32\Recovery (while in 7zip)


You can now resize your recovery partition
diskpart
list disk
sel disk<OS disk index of your windows boot drive, usually it is zero>
diskpart
list part
(info for GPT disk)

select part<WinRE partition index>
shrink desired=250 minimum=250
create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes =0x8000000000000001
format quick fs=ntfs label=”Windows RE tools”
list vol
exit (from diskpart)


Finally, run:
reagentc /enable
run the problem update (took a long time on my PC)

Hi! You are trying to shrink the Recovery Partition:
create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes =0x8000000000000001
instead of shrinking your main OS Partition by 250MB (should be at least 1024 MB)
This cannot work.

It worked for me and others.
