BitLocker Recovery Screen After KB5040442 & Workaround

Following the July 2024 security update (KB5040442), some Windows users are encountering a BitLocker recovery screen on startup. This article from MiniTool Software explains the issue and offers solutions.

BitLocker Recovery Screen After KB5040442 Update

Microsoft's July 9th, 2024 security update, while bringing improvements, has caused a bug resulting in a BitLocker recovery prompt before the system boots to the desktop. This requires the BitLocker recovery key to proceed. Microsoft acknowledges the issue, confirming it affects various Windows versions:

• Client: Windows 11 (23H2, 22H2, 21H2), Windows 10 (22H2, 21H2)
• Server: Windows Server 2022, 2019, 2016, 2012 R2, 2012, 2008 R2, 2008

The problem stems from the enabled Device Encryption setting.

Resolving the BitLocker Recovery Screen

The simplest solution is entering your BitLocker recovery key. If you don't have it, retrieve it via the BitLocker Recovery Key portal using your Microsoft account.

Temporary Workarounds

While Microsoft works on a permanent fix, consider these temporary solutions:

• Pause Windows Updates: Open Windows Settings (Win I), navigate to Windows Update, and select "Pause for 1 week." (See this article for additional update pausing methods: How to Stop Windows 11 Automatic Updates).
• Disable Automatic Device Encryption: For users unwilling to repeatedly enter recovery keys, modifying registry and ISO files can prevent automatic drive encryption during Windows installation. (Detailed instructions are available here: How to Prevent Windows 11 From Encrypting Drives During Installation).

Data Recovery Recommendation

If data loss occurs due to this issue, MiniTool Power Data Recovery is recommended. This software offers a free edition for recovering up to 1GB of data, and a bootable edition for recovering data from unbootable systems.

Conclusion

The BitLocker recovery screen after KB5040442 can be addressed by retrieving and entering the recovery key. Until Microsoft releases a complete fix, pausing updates or disabling automatic encryption are viable temporary workarounds. Remember to utilize data recovery software if necessary.
