Hi @nojoke0310,

this is a common issue during updates, and here are some troubleshooting steps you can try:

  1. Windows Update Troubleshooter:
    Microsoft provides a step-by-step guide to fix problems during updates.
    Windows Update Troubleshooter - Microsoft Support

  2. Clear Windows Update cache:

    • Stop Background Intelligent Transfer Service and Windows Update in the Services menu.
    • Navigate to C:\\Windows\\SoftwareDistribution\\Download in File Explorer and delete its contents.
  3. Run DISM and SFC commands:
    Open Command Prompt (CMD) as an administrator and enter these commands:

    • DISM.exe /Online /Cleanup-image /Restorehealth
    • sfc /scannow
  4. Re-download the update file:
    Delete the original files and download them again.

Hi. it's a bit complicated I'm ignoring this error for now, it applies to Windows10 computers.

Check it out:

I would like to add that trying to fix it yourself is a waste of time in this case.

Hello! You've posted your question in the Tech Community Discussion space, which is intended for discussion around the Tech Community website itself, not product questions. I'm moving your question to the Windows 10 space - please post Windows 10 questions here in the future. 

In case you observe this error for KB5034441 update and you will see update failures for this update, then it is known issue.

@Reza_Ameri  

If I interpret correctly, the attack vector must be physical contact with the computer - remote violation is not possible?

Correct, explanation of Physical is "The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent." , it is still important and hopeful a solution will be available soon.

@Reza_Ameri 

Thank you, it means that the threat is very low and waiting for an official fix is a good thing.

I'm just ignoring this error.

:clockwise_vertical_arrows: Security Update Guide - Loading - Microsoft

"

What kind of security feature could be bypassed by successfully exploiting this vulnerability?

A successful attacker could bypass the BitLocker Device Encryption feature on the system storage device. An attacker with physical access to the target could exploit this vulnerability to gain access to encrypted data."

Generally all vulnerabilities are important, and you may use workaround and modify the partition if you are working in environment which you dealt with sensitive data. However, if you could wait for official wait it would be better. However, it really depends on your security assessment and you have to see whether you need to resolve this update right away or wait for official fix, this is something you should decide.

I had the same issue regarding the update error (0x80070643), and managed to get the issue fixed by following these steps from here: https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-t...
Yes, this is a workaround but there is a risk of data lost if there is a mistake , so it is recommended to backup data before following this method. In addition, Microsoft is working on a fix and hopefully there would be easier solution in the future.

@JohanLeo I tried nonstop to increase the partition, but it still fails. Unsure why - but I think it's the ORDER (place) in which the WinRE partition lives.

The instructions do not work for all.

I'm worried if I do any more, I'll damage my drive map/boot record.

Make sure report this issue using the Feedback Hub app.
Did you followed the steps in the article one by one?

@lindros99 Same happened to me, glad I made a backup of all my partitions, restore worked. MS needs to issue a proper fix

Yes, I "followed the steps in the article one by one."
Regardless, using simple math, 558 is greater than 522. This is messed up.
The "solution" is very narrowly focused, and as you can see - I previously had TWO WinRe partitions - now I have one, with 500MB unallocated.
Hi everyone.
I am having exactly the same issue than You.
The positions are different for me on the first disk.
Partition 1 is Recovery and partition 2 is system and Partition 3 is the rest of the disk. I am able to touch only the 3rd one to make free space, but when I follow the guidelines to increase the partition size, I am not able to create a new partition that inclue the new available space, as they are not next to each other, as I understand.
I am now in May and the problem is still here. Does anyone is still having the same issue than me ?
(sorry for my crappy English, I am coming from France and I am fare to be billingual)
Pause the update or roll back to the previous version. Then wait for next major update.

@luladineace 

Perfect, Thank you very much for your time, I will wxait for it
Hopefully they did not forget to fix this issue
