Microsoft fixes Windows 11 24H2 updates failing with 0x80240069 error

Microsoft has resolved a known issue preventing the August 2025 Windows 11 24H2 cumulative update from being delivered via Windows Server Update Services (WSUS).

Introduced almost twenty years ago, WSUS helps IT administrators defer, approve, and schedule updates for Microsoft products on enterprise networks from a single local update server, rather than having each endpoint update from Redmond's servers.

Microsoft confirmed the known issue yesterday evening, one day after widespread reports from Windows administrators regarding 0x80240069 errors when installing the Windows 11 24H2 KB5063878 update.

Those affected also reported finding new entries in the Windows Event Log, which included "Service wuauserv has unexpectedly stopped" and "The Windows Update service terminated unexpectedly" messages.

"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)," the company said in a Wednesday Windows release health update.

"Home users are unlikely to experience this issue, as WSUS is designed for use across business and enterprise environments."

Fix pushed via Known Issue Rollback

While a fix for this update issue is not yet being shipped to all customers through Windows Update, Microsoft has started rolling one out automatically through Known Issue Rollback (KIR) to all enterprise-managed devices.

To address the bug, Windows administrators must install the Known Issue Rollback Group Policy on impacted enterprise-managed devices running Windows 11 24H2.

To deploy this policy, admins must use the Group Policy Editor to select the Windows version they want to target in the Local Computer Policy or the Domain Policy on the domain controller, and then restart the affected devices to apply the group policy setting.

You can find additional guidance on deploying and configuring KIR Group Policies on Microsoft's documentation website.

As a workaround for those who prefer to wait for the fix to be included in a future Windows update, Microsoft said that affected customers can also manually install the KB5063878 cumulative update via Windows Update or the Microsoft Update Catalog.

This isn't the first time admins have experienced problems delivering a Windows 11 update via WSUS in recent months.

In April, Microsoft confirmed an identical issue after enterprise customers reported being plagued by the same Windows Update Service errors when trying to update Windows 11 22H2/23H2 systems.

The company addressed the issue in May by rolling out a fix through Known Issue Rollback (KIR) to all enterprise-managed devices.
