Windows update (KB5034441) Error (0x80070643)

There's a Windows Update Show/Hide tool that will let you hide the problematic update:

Download Microsoft Show or Hide Updates Troubleshooter - MajorGeeks

I was able to use it only because I was given temporary admin rights to my work PC. Otherwise I can't even download this file, let alone run it.

Since hiding it, I don't get the error or even see that update try to run anymore. I do get the daily security intelligence updates but am not sure other ones are getting through. Maybe there haven't been any this week (.NET, or other system/quality updates).

Use this support this will solve you issue. Follow step by step and should be able to get the update to work

Not working at my end. Still have the same error. Guess I'll have to deactivate updates for a while...

I have tried this suggested resolution of the 0x80070643 on the 2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441) update. It does not work on most Win10 PCs. It does work on some. There are many, many users waiting for MS to fix this Update or just forget it. Not sure exactly why it does not work on some machines. This is why MS just states wait and we are investigating. They can't fix it either.

I have the same problem. I have several older Win 10 PCs that did accept this update, and more that did not accept it. There is something to the posts about Win RE (Windows Recovery) Partition size and perhaps the existence of a previous recovery with the winre.wim file **** on the partition "System Reserved Partition". The older PCs that I have, that accepted this update, have a real (valid) Windows Recovery Partition with files and a real recovery present. You can check this with a program like Mini Tool Partition to see the size. Or you can use Disk Management in Windows to see free size. It looks like the System Reserved / Recovery Partition is about 30MB (this was something the original Windows load made), I know this seems small. The PCs I have that will not accept this update will also not allow a Windows Recovery to be created. The Error "unable to locate needed files" has many, many posts written, and none of them seem to work to resolve, save a complete Windows Reinstall (erases everything you have). On one older machine (with MBR and Bios) I followed KB5028997 directions (kindof), I shrunk the main partition 1500MB (this produced a 1.44GB (1440MB) Partition that was named Windows RE Tools . Essentially an EMPTY Partition. I made sure the reagentc /enabled was active and working when done. So Disk 0 Partition 1 is System Reserved 579 MB Partition, then Main Boot, Page, etc is Partition 2 690GB, and last Windows RE Tools 1.4GB Partition 3. Hope MS fixes this soon. Not recommended to move Partitions unless you know what your doing - dangerous.
