Microsoft corrects update error 0x80070643 in Windows 10 and Server 2022

Last week, Microsoft admitted that the Windows updates from April could display an error message on Windows 10 and Windows Server 2022 systems. In this context, the error code 0x80070643 appeared again, which has already caused annoyance in the past.

At least Microsoft can give the all-clear for the cases currently occurring under Windows 10 22H2, 21H2 and Server 2022. In the Windows Release Health Notes, the Redmond-based company writes that it has got the problem under control with updated update packages. "If you install KB5057588 after April 21, 2025 at 2 am Pacific Time [equivalent to 11 pm Central European Summer Time], you will no longer see the incorrect error message about the installation error. If you have already installed the update, you will not be offered it again. You can check the status of this update with the Dism /Online /Get-Packages command," Microsoft's developers now write.

Supposedly faulty installation of the update

On Tuesday last week, it became known that the update KB5057588 for the Windows Recovery Environment of the affected Windows versions frequently caused an error message. "After installing this update, you may see the following error message on the Windows Update settings page: 0x80070643 – ERROR_INSTALL_FAILURE. This error message is incorrect and does not affect update or device functionality," Microsoft explained.

The developers also explained that Windows Update could continue to show the update as failed. This would be the case until the next daily scan, when it would no longer be offered and the error message would be automatically deleted.

In this case, Microsoft was able to quickly remedy the incorrect display. However, updates for Bitlocker encryption in the Windows Recovery environment actually failed last year. In the end, Microsoft gave up trying to find and distribute an automated solution to the problem.
