For anyone interested in the history behind the NT kernel I recommend a book called "Show Stopper!: The Breakneck Race to Create Windows NT and the Next Generation at Microsoft" by G. Pascal Zachary - really enjoyed it.
I think the Windows NT kernel is a very underrated piece of technology - the reason it was unstable in the beginning is due to a corporate top-down decision: the hardware of the time was limited so they included GDI stuff in the kernel (crappy code not written by Cutler's team).
