Major Update Fix for Windows 11 Users!

Microsoft has unveiled a crucial fix for a persistent error affecting Windows 11 users trying to upgrade to the 24H2 feature update. Users encountered the frustrating 0x80240069 error after installing the April 2025 security updates, particularly when using Windows Server Update Services (WSUS).

What is WSUS and Why Does It Matter?

Introduced nearly two decades ago, WSUS allows IT administrators to manage updates for Microsoft products across vast enterprise networks from a centralized system, ensuring that devices don’t need to fetch updates individually from Microsoft's servers.

Widespread Reporting and Confirmation

In late April, Microsoft confirmed widespread reports of upgrade issues, as frustrated users took to online platforms like Reddit to voice their concerns. The error manifests when attempting to update systems on Windows 11 23H2 or Windows 11 22H2 versions.

Who's Affected?

Fortunately for home users, the update issues primarily impact those in enterprise environments utilizing WSUS, making the problem less prevalent in personal computing scenarios.

Understanding the Issue

According to Microsoft, if your device had installed the April monthly security update released on April 8, 2025 (starting with KB5055528), it might be unable to initiate or complete the download of the 24H2 upgrade. Error messages may highlight that the Windows Update Service (wuauserv) has unexpectedly stopped.

How to Fix It

For those impacted, a fix is now rolling out via Known Issue Rollback (KIR) for all enterprise-managed devices. IT admins can resolve the issue by implementing the KIR Group Policy to targeted endpoints running Windows 11 22H2 and 23H2.

Steps to Deploy the Fix

Admins should access the Group Policy Editor, select the appropriate Windows version in the Local or Domain Policy, and then restart the affected devices to apply the new settings. For detailed instructions, Microsoft offers extensive guidance on its documentation site.

Beyond the Fix: Upgrading Policies Under Review

Additionally, Microsoft is addressing a separate "latent code issue" that erroneously upgrades some PCs to Windows 11 despite existing Intune policies meant to prevent such changes. Stay tuned for updates as Microsoft continues to enhance the upgrade experience!
