[This is preliminary documentation and subject to change.]
The DWbemClassObject.Delete method deletes the specified property and all of its qualifiers. Delete operations for properties are possible only on class definitions, since instances cannot have contents that are different from the owning class.
It is not possible to delete a property that was inherited from a parent class. However, if you specified an override default value for a property inherited from a parent class, it is possible to revert to the parent's default value by invoking this method. In this case, WBEM_S_RESET_TO_DEFAULT is returned. You cannot delete System properties.
