Hi,
Since the issue is affecting multiple clients and only occurs when installing the July 2026 monthly update from WSUS, this is less likely to be a client-side corruption issue and more likely related to the update deployment or WSUS environment. Error 0x80244007 is a Windows Update Agent error commonly associated with problems processing update metadata or communicating with the WSUS server, rather than the installation of the update itself.
I would first verify whether the affected clients can successfully install the same cumulative update directly from Microsoft Update. If they can, the focus should shift to the WSUS server. On the WSUS side, review the SoftwareDistribution.log, WindowsUpdate.log (on the client), and Applications and Services Logs > Microsoft > Windows > WindowsUpdateClient > Operational for the failing clients. Also confirm that the July 2026 update has synchronized successfully, its metadata is intact, and that IIS, WSUS synchronization, and content download completed without errors.
