IWbemClassObject::Delete method (wbemcli.h)

The IWbemClassObject::Delete method deletes the specified property from a CIM class definition and all of its qualifiers. Because instances cannot have contents that are different from the owning class, delete operations for properties are only possible on class definitions. If you invoke Delete on a property in an instance, the operation succeeds; however, rather than removing the value, it is simply reset to the default value for the class.

It is not possible to delete a property inherited from a parent class. However, if an override default value for a property inherited from a parent class was specified, 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.

System properties cannot be deleted.
