Earlier today, Microsoft shared details about how one of the most crucial Windows features could lead to the theft of BitLocker-encrypted data. The company also added that the vulnerability has been patched with the latest August 2025 Patch Tuesday updates: Windows 11 (KB5063878, KB5063875) and Windows 10 (KB5063709 / KB5063877 / KB5063871 / KB5063889).
However, the new patches are far from flawless as they are causing installation issues. In a new message, Microsoft has confirmed that the KB5063878 update is leading to install failures when installed from Windows Server Update Services (WSUS) and System Center Configuration Manager (SCCM). Upon the failure to install the update, Windows throws up the error code "0x80240069".
Thankfully, home users are unlikely to be affected by this, Microsoft notes, as the issue mainly impacts enterprise and business users.
While Microsoft says that it is working to resolve the issue through a future Windows Update, currently, the tech giant has shared a workaround. A known issue rollback (KIR) has been shared that can be applied with a Group Policy, the details for the same have been given below:
Group Policy downloads with Group Policy name:
- Download for Windows 11, version 24H2 -- Windows 11 24H2 and Windows Server 2025 KB5063878 250814_00551 Known Issue Rollback
The special Group Policy can be found in Computer Configuration -> Administrative Templates -> . For information on deploying and configuring these special Group Policy, please see How to use Group Policy to deploy a Known Issue Rollback.
Microsoft says that once the issue has been fully resolved via the future Windows Patch, administrators will no longer need to deploy the KIR Group Policy above. You can find the issue entry here on the Windows Health dashboard page on Microsoft"s official website.
Update, August 17 2025, 12.00 GMT: Microsoft has resolved the issue. The company has added that users no longer need to add the Group Policy that was provided as workaround. It writes:
