Tiny portable private program

Let’s start off with I’m thinking out of the box at the moment.

I would like a program, which does the same as whatpulse client, but then running as a service or something, no need to install.

Because at work we use alot of type’s, clicks and so on. I was wondering if it was possible to create a program that registers all this with automatic pulsing without - or physical program, so as a service or as a program that can’t be opened or edited. Well you got the point, your boss shouldnt be able to see it’s running.

Kind regards,
