If the CrowdStrike fiasco wasn’t enough, Microsoft’s Windows latest July 2024 security update is sending Windows PCs into BitLocker recovery mode once they are booted.
For those unaware, Microsoft released its latest July 2024 Windows mandatory security update (KB5040442) on July 9, 2024, for Windows 11 version 23H2 and version 22H2, as well as Windows Server.
This update brings several improvements to existing features, enhancements to the Copilot app, security and account management, the latest bug fixes, and much more.
While some faced installation problems, those who successfully installed the KB5040442 update were asked to enter their BitLocker recovery key after rebooting the PC after installation.
For those unaware, BitLocker recovery is the process by which access to a BitLocker-protected drive can be restored if the drive doesn’t unlock using its default unlock mechanism.
“After installing the July 2024 Windows security update, released July 9, 2024 (KB5040442), you might see a BitLocker recovery screen upon booting your device,” Microsoft explains on the Windows release health dashboard.
“This screen does not commonly appear after a Windows update. You are more likely to face this issue if you have the Device Encryption option enabled in Settings under Privacy & Security -> Device encryption.”
Those affected by this issue may be prompted to enter the recovery key from their Microsoft account to unlock the drive to allow the device to boot normally from the BitLocker recovery screen.
The platforms affected by the BitLocker recovery issue include Windows 11 version 23H2, Windows 11 version 22H2, Windows 11 version 21H2, Windows 10 version 22H2, and Windows 10 version 21H2.
Similarly, several versions of Windows Server too are affected, such as Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008.
Microsoft is investigating the issue and is expected to provide an update when more information is available. However, the Redmond giant has provided a workaround that can help users start up normally from the BitLocker recovery screen.
According to Microsoft, the device should be able to start normally from the BitLocker recovery screen once the recovery key has been entered.
To retrieve the recovery key, the user can log in into the BitLocker recovery screen portal with their Microsoft account, which provides detailed steps for finding the recovery key that is listed here: Finding your BitLocker recovery key in Windows.
