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 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 24H2 does not initiate or complete. Windows updates log can show error code 0x80240069, and further logs might include text similar to “Service wuauserv has unexpectedly stopped”…
