It promoted a "toolbox" approach to system utilities. extending the default (Unix) security model as well as The microkernel is simple to extend as new services are added in user address space, which is separate from kernel space, and thus the kernel doesn't need to be updated. activated (sometime called protected mode or paging enabled). Another drawback to monolithic kernel design is that the kernel code has to be modified to add features or fix bugs.
