This goes back to the days of DOS, when once your application started, you could do anything you pleased, as long as you put the OS kernel back to its clean state before you exited. Dave Cutler fought tooth and nail against any attempts to insert hooks in the NT microkernel, or to muddle the layered design. But after Dave left day-to-day NT development, things got muddied up. -Paul W.
