Microkernels seem to be having a new wave of popularity recently (new microkernel based OSes being made, apple slowly turning XNU into a microkernel)

Windows uses a hybrid kernel, but that still means drivers have access to the entirety of kernel space

Microkernels are so much more secure (when done properly with IOMMU and everything)

However, kernel based anticheats won’t work with microkernels (since most microkernels aren’t modular)
