Q. Does Windows XP offer any user-mode processes that enable it to run programs developed for other operating systems? Describe two of these subsystems.
Answer: Environmental subsystems are user-mode processes layered in excess of the native executable services to enable Windows XP to run programs developed for other operating systems.
