Microsoft has successfully addressed a significant issue that was hindering the delivery of the August 2025 Windows 11 24H2 cumulative update via Windows Server Update Services (WSUS). This platform, which has been a cornerstone for IT administrators for nearly two decades, allows for the centralized management of Microsoft product updates across enterprise networks. Instead of each device connecting directly to Microsoft’s servers in Redmond, WSUS enables a more streamlined approach by allowing updates to be managed from a single local server.
On Wednesday evening, Microsoft acknowledged the problem, which had been reported by numerous Windows administrators experiencing the 0x80240069 error code during the installation of the Windows 11 24H2 KB5063878 update. Many users noted the appearance of new entries in the Windows Event Log, including messages indicating that the “Service wuauserv has unexpectedly stopped” and “The Windows Update service terminated unexpectedly.”
The company clarified, “The August 12, 2025 Windows security update for Windows 11, version 24H2 (KB5063878), might fail to install with error code 0x80240069 when installed via Windows Server Update Services (WSUS).” They also pointed out that home users are unlikely to face this issue, as WSUS is primarily designed for business and enterprise environments.
Fix pushed via Known Issue Rollback
While a comprehensive fix for this update issue is still in the pipeline for general distribution through Windows Update, Microsoft has initiated an automatic rollout of a solution via Known Issue Rollback (KIR) specifically for enterprise-managed devices. To implement this fix, Windows administrators are required to install the Known Issue Rollback Group Policy on the affected devices running Windows 11 24H2.
To deploy this policy, administrators should utilize the Group Policy Editor to select the appropriate Windows version within the Local Computer Policy or the Domain Policy on the domain controller. A restart of the impacted devices will be necessary to apply the new group policy settings. For those seeking further assistance, Microsoft provides detailed guidance on deploying and configuring KIR Group Policies on their documentation website.
For users who prefer to wait for the fix to be integrated into a future Windows update, Microsoft has suggested an alternative: affected customers can manually install the KB5063878 cumulative update through Windows Update or the Microsoft Update Catalog.
This incident is not the first of its kind, as administrators have faced similar challenges with Windows 11 updates via WSUS in recent months. In April, Microsoft confirmed a comparable issue after enterprise customers reported encountering the same Windows Update Service errors while attempting to update Windows 11 22H2/23H2 systems. The company successfully addressed that problem in May by rolling out a fix through Known Issue Rollback (KIR) for all enterprise-managed devices.
