Unable to update (KB5034441) using below links

You don't need to expand the WinRE partition because its capacity is 893 MB, which should be sufficient.

Please start a new thread so that I can post specific instructions for your system.

Also, see my post below - pasted from another thread:

Microsoft is working on a fix. Until then, you may ignore the Windows Update error 0x80070643 and wait for an official fix.

Important: Follow the workaround only if you're comfortable with the diskpart console tool because it can be a risky procedure. Otherwise, please start a new thread and seek the assistance of an IA or moderator.

Workaround: Resizing the Recovery partition to 750 MB or more will fix the issue. The error occurs due to a lack of free disk space in the Recovery partition.

KB5028997: Instructions to manually resize your partition to install the WinRE update - Microsoft Support: https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

Caveat: The above Microsoft article assumes the Recovery partition is situated next to the OS partition. That's not necessarily the case in many systems. So, a different approach has to be followed on systems where the Recovery partition is not located near the OS partition. In that case, please start a new thread and seek the assistance of an advisor or volunteer moderator.

Hi Ramesh, after running the command "shrink desired=250 minimum=250", I cannot see any WinRe partition to carry on to the next step:

To select the WinRE partition, run sel part<WinRE partition index>

I see only this:

The shrink command show this in diskpartition (it creates 252mb unallocated space which I can't seem to do anything with now):

Where is the WinRE index mentioned, and how can I resolve this please?

Yesterday they said that they are working on this update. We will get an update soon.
