Windows 11 Lock Screen Spotlight Not Updating (Error 0x80004002)

Your tests already isolate this beyond the per-user Spotlight cache: a fresh account fails, the Assets folder stays empty, and both ContentDeliveryManager tasks return 0x80004002, which is an interface-registration failure. Desktop Spotlight working rules out a general service outage. Stop broad package re-registration, since file-lock and core-package errors can leave servicing in a less predictable state. Install pending Windows and Microsoft Store updates, restart, set the lock screen to Picture, then switch it back to Windows spotlight and retest the scheduled tasks. If the HRESULT remains, use Settings > System > Recovery > Fix problems using Windows Update > Reinstall now. Microsoft documents that repair as reinstalling the Windows version while preserving apps, files, and settings, so it is safer than a reset and is not a feature upgrade. If the option is unavailable on a managed device, collect Feedback Hub diagnostics and have IT open a Microsoft support case.
