windows isn't real

 well i guess it kinda isn't real

so random discovery time:


when hyper v is enabled on windows, it runs underneath windows. as in, its not just part of the kernel, it replaces it.. so when windows is running on a machine with hyper-v enabled, the "host" is actually a special vm that has direct access to all of the I/O and PCIe. so no code running in windows (other than hyper v itself) runs on the bare metal when hyper v is on.
