Windows actually uses a cpu feature for kernel patch protection right? I remember trying to figure out why Linux doesn't.

  On modern Windows, it actually always runs as guest on Hyper V, and thus many such protection mechanisms ping back on virtualization. Secure kernel and driver guard are another features with similar protection level.

    Are you talking about VBS/HVCS? Isn't that optional or is it on by default for kernel stuff?

      Optional on Windows 10, compulsory on Windows 11. One of the reasons for the hardware requirements.
