Microsoft has released a fix for Windows 11 and Windows 10 devices in relation to a BitLocker bypass security flaw. The company has developed two sample PowerShell scripts that will essentially allow system admins and IT administrators to automate the Windows Recovery Environment (WinRE) update process to mitigate a BitLocker security bypass vulnerability (CVE-2022-41099).

If you are wondering about the differences between the two scripts, Microsoft says that its first script, the recommended one, is more robust and applies to Windows 10 version 2004 and later, as well as Windows 11. The second, general script, is mainly for devices running Windows 10 version 1909 and older, but it too works on all versions of Windows 11 and Windows 10.

You can find more details regarding the script as well as their installation process on Microsoft's official advisory on the topic under KB5025175.
