Microsoft has confirmed an issue affecting Windows 11 versions 22H2 and 23H2 after installing the April 8, 2025 cumulative update KB5055528. This problem prevents the upgrade to version 24H2 from downloading via Windows Server Update Services (WSUS).

Users have reported that the update either fails to start or cannot complete successfully. When this happens, the system generates error code 0x80240069 . Additionally, the update log displays a message similar to:
"The wuauserv service stopped unexpectedly."
WSUS is primarily used in corporate environments, so regular users are unlikely to encounter this issue. Microsoft engineers are actively investigating the root cause of the problem.
The issue says:
Windows 11, versions 24H2 might not download via Windows Server Updates Services
Devices which have installed the April Windows monthly security update, released April 8, 2025, or later (starting with KB5055528) might be unable to update to Windows 11, version 24H2 via Windows Server Update Services (WSUS). WSUS allows Servers with the WSUS role to defer, selectively approve, and schedule updates for specific devices or groups across an organization.
As part of this issue, the download of Windows 11, version 24H2, doesn't initiate or complete. Windows updates log can show error code 0x80240069, and further logs might include text similar to "Service has unexpectedly stopped".
Home users are unlikely to experience this issue, as WSUS is designed for use across business and enterprise environments.
Microsoft doesn't officially offer any workaround to date. You can track the issue status here.
