Problem in a nutshell. If an OS can't tell when I explicitly ask for
something, then it needs to be torn down and rebuilt so that it can.
Then you need to discard every operating system ever built, except for the
occasional scientific curiosity(*).
Let's take keyboard input as an example. You press a key, two partial
circuits are joined, and a current flows. This signal travels into a hole in
the back of your computer, and eventually hits the I/O bus in your system.
After that, everything's software - and there are numerous layers of the
software between the signal's first arrival into the system and the target
application.
So, no, your OS can't tell when you explicitly ask for something, as opposed
to when "software" asked for it, because it's all software from the moment
that signal is detected at the I/O bus.
Throw away your computers, because you're asking for them to do something
that you don't understand is impossible.
Alun.

(*) Microsoft themselves have some of these scientific curiosities under
development - the "Next Generation Secure Computing Base" at one time had
the concept of a mouse and keyboard that would cryptographically sign every
keystroke, every mouse move, every button click. Needles to say, with that
kind of overhead, we aren't going to be seeing that in a consumer OS any
time soon.
