IWbemClassObject::SpawnInstance method (wbemcli.h)
Use the IWbemClassObject::SpawnInstance method to create a new instance of a class. The current object must be a class definition obtained from Windows Management using IWbemServices::GetObject, IWbemServices::CreateClassEnum, or IWbemServices::CreateClassEnumAsync Then, use this class definition to create new instances.
A call to IWbemServices::PutInstance is required to actually write the instance to Windows Management. If you intend to discard the object before calling IWbemServices::PutInstance, simply make a call to IWbemClassObject::Release.
Note that spawning an instance from an instance is supported but the returned instance will be empty.

[in] long lFlags,
[out] IWbemClassObject **ppNewInstance
);
Parameters
[in] lFlags
Reserved. This parameter must be 0.
[out] ppNewInstance
Cannot be NULL. It receives a new instance of the class. The caller must invoke IWbemClassObject::Release when the pointer is no longer required. On error, a new object is not returned and the pointer is left unmodified.
