I'm a software developper, and my company gave me a Laptop for my work.
The other day, i wanted to receive feedback from a collegue about stuff i was working on. I needed to record my screen to show what i wanted to show, and i used the windows+g shortcut in order to do so.
Since then, each time i launch a program (firefox for example), an annoying sliding pop-up reminds me that i can use the game bar to take screenshots and record my gameplay. (But i don't want to record anything anymore, especially considering how fast firefox's gameplay gets boring.)
I used google in order to see what i could do about this. And google answered me :" find the option in the control panel that allows you to disable all game related fonctions". i.e : the xbox option. (Or the one with the x-box logo, at least.)
Problem is, as you can see in this (french) screenshot, the gaming/xbox option is nowhere to be found.

I have admin rights on this machine, and i can edit the register if necessary. What can i do about this?
