The system provides three categories of objects: user, graphics device interface (GDI), and kernel. The system uses user objects to support window management, GDI objects to support graphics, and kernel objects to support memory management, process execution, and interprocess communications (IPC). For information about creating and using a specific object, refer to the associated overview.
