STATUS_WMI_ALREADY_ENABLED
The WMI GUID is already enabled
This status is returned when an enable request targets WMI collection or events that are already active for the GUID. The provider state is therefore different from an unsupported request: the enable operation exists, but applying it again would not create a new transition.
Check whether multiple consumers independently assume they own provider enablement. WMI providers often have to track enable/disable state carefully because event generation may allocate resources or arm hardware collection. A balanced request sequence is more useful than blindly ignoring every duplicate enable.
What to inspect
- Identify the GUID and whether events or collection were enabled.
- Correlate the response with earlier enable requests from all consumers.
- Verify that disable occurs only when the corresponding ownership/reference is released.
