Microsoft is addressing issues with installing the KB5034441 security update, which patches a BitLocker vulnerability. The update can fail on systems with a small Windows Recovery Environment (WinRE) partition, displaying the 0x80070643 error. Microsoft offers manual partition resizing instructions and a PowerShell script to automate the update process, also providing guidelines for preventing further installation errors.
From the meeting notes, the key takeaways are:
– Microsoft is addressing a known issue causing 0x80070643 errors when installing the KB5034441 security update, particularly on systems with a Windows Recovery Environment (WinRE) partition that’s too small.
– A workaround provided by Microsoft involves detailed instructions on how to resize WinRE partitions until a permanent fix is available.
– Microsoft has released a PowerShell script to automate the update of the WinRE partition to fix the CVE-2024-20666 flaw related to BitLocker, which can be vulnerable to attacks exploiting the BitLocker flaw.
– After running the script, using Microsoft’s Show or Hide Tool to hide the KB5034441 update is recommended to prevent repeated installation attempts and error displays.
– It’s emphasized that if resizing WinRE partitions manually, backing up data is highly recommended due to the potential risk of partition damage during the process.
