I have same error when trying to update the same patch.

Totally agree with this comment.

Having same Issue with KB5034441 Update 01-09-2024 fails to install 0x80070643.

Followed the above steps except for in-place upgrade (since my PC does not have hardware to run windows 11). Problem persists.

I just started running into this, and there's this blurb in the description of the update: IMPORTANT Some computers might not have a recovery partition that is large enough to complete this update. Because of this, the update for WinRE might fail. In this case, you will receive the following error message: Windows Recovery Environment servicing failed. (CBS_E_INSUFFICIENT_DISK_SPACE) To help you recover from this failure, please follow Instructions to manually resize your partition to install the WinRE update . Known issue Because of an issue in the error code handling routine, you might receive the following error message instead of the expected error message when there is insufficient disk space: 0x80070643 - ERROR_INSTALL_FAILURE Source: https://support.microsoft.com/en-us/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8 I tried the process of resizing the recovery partition and ran into an interesting error when I tried to re-enable it. Windows reported it can't enable it while Bitlocker is enabled. So I'm wondering if this patch to fix a Bitlocker-related vulnerability requires Bitlocker to be disabled and the device decrypted before it will work. Thoughts?
