Is there a way to take a screenshot, that satisfy following requirements:

* Full screen screenshot is taken when pressing `PrtSc` button
* Screenshot is taken immediately, there is no further configuration / selection to do after pressing the button
* It is automatically saved to a preconfigured folder I can change
* It does not change focus - that is it does not pop up the folder (or anything else) after screenshot is taken
* If a third party program is used, it should be free

I know that `⊞ Win`+`PrtSc` does that, but I need to be able to do it with a single `PrtSc` press, not with the combo.

Is this possible? How?

I'm asking for a friend, who used to take screenshots this way on his old computer, that was set up this way by an unknown person. On his new computer it's no longer working because it was not set up this way. It's difficult for him to change his habits, he already tried and reported that it is not working to his satisfaction. How can I help him?

Edit: not a dupe!

Basically the only think in common, that it's also about printing screen and nothing else: the linked question asked about regions, this one asks about full screen, the linked question asks for mouse usage, this one asks for keyboard usage. The answer to linked question uses the two-key combo, which is specifically out of scope for this question.
