WU_E_INVENTORY_WMI_ERROR
WU_E_INVENTORY_WMI_ERROR means a Windows Update inventory rule tried to enumerate a WMI class and the WMI operation failed. This can affect update applicability because the agent cannot collect the device fact required by the rule.
What to check
- Use the update log to identify the relevant inventory phase and any underlying WMI error.
- Check the Windows Management Instrumentation service, event logs, permissions, and repository health using a supported WMI diagnostic workflow.
- Avoid rebuilding the WMI repository as a first response; it can create additional management problems and should follow evidence of repository damage.
