Access to hardware bypassing the API under Windows - is it possible or not?

Question

API

It seems to have clearly stated. Is there a way?

Answer 1

Yes Easy. You open the cover of the system unit / laptop with a screwdriver - and voila, access to the hardware without winAPI.
In short, vaguely formulated.

Answer 2

Can. From C#, through the System.Management classes. Works slowly.
