Update issue on 2022 server

Question

Hi, There was a download issue to the following update. Any help?

Answer 1

It was recently reported that the Windows Server 2022 Security Update KB5034439, which was released as part of Patch Tuesday to address a BitLocker encryption bypass (CVE-2024-20666), has been failing. The failure occurs when there are issues with the Windows RE partition and deployment, preventing the update from being installed. Indeed, a known issue has been identified with KB5034439. The update fails to install on a PC without a recovery partition, resulting in the error 0x80070643 ERROR_INSTALL_FAILURE. However, if your PC does not have a recovery partition, this update is not necessary. Therefore, in such cases, the error can be disregarded.
