Statistics hidden program how to

[CosminPerRam]

Hello there, i want to make an program in C++ SFML which to be always active, always hidden and always "recording". With that one i mean, i want to do a SFML window which is always active, cannot close it, only from task manager, always hidden, i dont want the user to see it and always recording, by that i mean to track for example: clicks count, keys count.

Here's what i know:

//Track Mouse Click Counter:
//..
case sf::Event::MouseButtonPressed:
     mousebuttoncounter++;
     break;

//Track Keyboard Key Pressed counter:
//..
case sf::Event::KeyPressed:
     keyboardkeypressedcounter++;
     break;

//How to see it only from task manager:
window.setVisible(false);

//With that above, if i run my program its not selected, by not selecting its doing nothing 

What i dont know:
-How to record what im doing, its no matter in what program i am now, i want it to record my statistics

Thanks in advance!
(If you are wondering why i need such a program, i want to track my statistics on my computer, and i have a problem with that, idk how to make it, the rest (auto startup, auto save, etc.) is simple.)

You're barking up the wrong tree with SFML. It will help you with none of what you want to accomplish.

Whatever you need to do will be specific to your operating system.
