design goals : extensibility the code must be written to comfortably grow and change as market requirements change. portability the system must be able to run on multiple hardware architectures and must be able to move with relative ease to new ones as market demands dictate. reliability and robustness the system should protect itself from both internal malfunction and external tampering. applications should not be able to harm the operating system or other applications. compatibility although windows nt should extend existing technology, its user interface and apis should be compatible with older versions of windows and with ms-dos. it should also interoperate well with other systems such as unix, os/2, and netware. performance within the constraints of the other design goals, the system should be as fast and responsive as possible on each hardware platform. is windows 2000 a microkernel-based system?although some claim it as such, windows 2000 isn´t a microkernel-based operating system in the classic definition of microkernels, where the principal operating system components (such as the memory manager, process manager, and i/o manager) run as separate processes in their own private address spaces, layered on a primitive set of services the microkernel provides.
