The update KB5034441 of Windows 10 continues to have problems even though Microsoft has been working “on a fix” for more than four weeks. KB5034441 is a mandatory update but cannot be installed due to error 0x80070643.
KB5034441 is a security update for Windows Recovery Environment (WinRE). This is an important release as it fixes a security issue that allows attackers to bypass the encryption of other Bitlocker partitions by exploiting the WinRe vulnerability.
As mentioned in a previous publication, Windows updates stop with the message “0x80070643 – ERROR_INSTALL_FAILURE”.
What causes the update to fail repeatedly?
Microsoft officials say the issue is strictly limited to computers with low recovery partition storage.
In a support document, Microsoft states that the security update for Windows Recovery needs at least 250 MB of free space on the recovery partition to install successfully.
Although Microsoft suggests increasing the partition size slightly, increasing it to 2 GB has proven to be much more efficient.
How to fix Windows 10 KB5034441 update problems by easily resizing the partition.
The company suggests something incredibly difficult, especially for novice users.
On the other hand, the company also published a PowerShell script that fixes the problem automatically, but make sure you install the “Safe OS Dynamic Update” via Microsoft Update Catalog before running the PowerShell script.
Download the script ή create your own
George is still wondering what he is doing here….
A month and 7 days have passed and Microsoft still hasn't found a solution
Good morning, because the specific problem is serious but also faced by users with very little knowledge, it would be good if the PowerShell script that is proposed was accompanied by an example with a random $packagePath so that everyone can understand how to configure it. Plus how they can perform it to fix the problem.
Thanks
Do not worry. MS will prepare a tool to automatically repair the issue.
