Because CLI/STI will allow you to take down the operating system,
something that cannot be allowed on NT. You could argue that it
should be allowed for administrators, but it would have to be
emulated like on 9x then...

Anyway, if you want almost the same kind of performance on NT,
you should use SetPriorityClass with REALTIME_PRIORITY_CLASS
and SetThreadPriority with THREAD_PRIORITY_TIME_CRITICAL, it
will almost let you lock up NT (except for hardware IRQs), but
of course requirse admin privs. It won't fail with non-admin
privs though, it will just set the priority class to the
highest dynamic possible.

Easy to see why you think windows suck, though, if you've
never dealt with NT. Takes somewhat getting used to, but it's
a much better system.
