UnregisterEvents
The UnregisterEvents command removes the event handlers used by FeatureInspector, and it will no longer respond to changes in the active documents.
The UnregisterEvents command calls the UnregisterEventCommand method of the Commands class. This method accesses the static Instance property of the EventRegister class to call the UnregisterEvents method. This method removes all the event handlers assigned by RegisterEvents.
