If you mean privilege levels, there are four of them (ring3-ring0) - when speaking of Intel 80X86 with X>2

In fact Windows systems use just two of them - ring3 (apps) and ring0 (system, drivers...). In ring3 you can't do some things (privileged) so that is why everyone digging deep must be in ring 0.
