Install error - 0x80070643 Windows 10, version 21H2 and 22H2

I was seeing the problem on 3 PCs that have been migrated to SSDs with Samsung Magician, so I wonder if this problem may be a side-effect of the re-partitioning that happens during the migration process.

exactly! You have to release your overprovisioning-partition with Samsung Magician. Then re-partitioning using command shell or any partition-manager will work

I don't think, it's needed or critical / important enough... I will just let it sit there, until Microsoft decides to withdraw their [BEEEP] and sends a new, better update. But why Microsoft don't twithdraw it, I don't know......

I can always check for new updates by clicking on the "Retry"-button and the other updates that may come, will install

I also had an update on another computer with only Windows Defender, where the KB5034122 wouldn't install before deactivating Defender.

A computer, on my working place, also with only Windows Defender deactivated, ate them all with pleasure!!!!!!!

I'm on Windows 10 FYI

This recent update causing my GPU driver crashing, fan speed going 100% for no reason. I had to repair framework. I had to use sfc /scannow command and framework repair tool smdh. I suggest doing all that first before doing below:

Guys, try installing free edition of easeus partition master to easily "move" the recovery partition using drag and drop feature to add the size. Click on recovery partition and click resize option. The software won't apply instantly once you arranged it, so you can change your mind before click second confirmation. So make sure using scandisk health check before doing this.

My recovery partition were about 500mb with 88mb free iirc. I added 250mb. Fix it so far. Arrow on attached pic showed my recovery partition location. Just click on it to adjust.

Luckily my SSD has space for provisioning so the process was easy.

If your recovery partition happen to be next to main partition, you can easily use this software with slider interface. Provided your main C drive has enough space, it will shrink to add rec partition needed. Iirc the process need restarting at first so the software can fix it before booting. Remember not to have any power failure during the process lol.

After repartition process, start again the update.

I fixed the error by enlarging WinRE partition by 250MB (Win10 22H2 - Disk partition type GPT) following below steps:

1. Search on start "Create and format hard disk partitions" and shrink 250MB from the partition next to partition Healthy (Recovery...)

2. Open cmd (Admin) and run reagentc /info . If WinRE is enabled, run reagentc /disable, else continue.
3. Run diskpart followed by sel Disk 0 (in my case, OS is located in Disk 0 as above image)
4. Run list part to search for WinRE partition
5. Run sel Partition n (n is the index of WinRE - Type Recovery)
6. Run delete partition override
7. Run create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac followed by gpt attributes =0x8000000000000001

*** If your partition type is MBR, just run only create partition primary id=27

8. Run format quick fs=ntfs label=”Windows RE tools”. Then run list part to check whether enlarged WinRE is created or not.
9. Run exit to exit from diskpart. Then run reagentc /enable

Now the WinRE partition is enlarged, just run Window Updates again.
