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

Question

I have been having this error for a long time now, it keeps saying "retry"after i click on it. Anyone know how to fix it?

Answer 1

I googled the actual KB and found this link: https://support.microsoft.com/en-gb/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8. It seems that it updates the Windows Recovery (WinRE) environment, and the tip about resizing the partition for that is valid. You can find the link to the instructions in the KB article I linked.

I did that and the installation passed.

Hi John

This error applies to all my windows machines, I thing there is mistake on Microsofts update. Lets hope its fixed quickly

Answer 4

I got it on both my Windows 10 machines. Looks like this is a disastrous update. I can't understand why MS can't produce meaningful error messages specific to a particular problem. It looks like many different issues can generate this same error code.

Answer 5

Resize the Recovery Partition.
