" Windows NT is much worse. The operating system is an example of completely ignoring security lessons from history. Things that are in the kernel are defined as secure, so smart engineering says to make the kernel as small as possible, and make sure everything in it is secure. Windows seems to take the position that since things in the kernel are defined as secure, than you should put everything in the kernel. "
