The Windows 10 Hidden Game Bar

Using the Windows key-G command, you can pull up the new and improved Game Bar. This lets you switch your Windows PC into gaming mode which pools system resources to the game and turns off notifications and lets you record and broadcast your gaming. It also has added panels for controlling your audio.

You can also search for the Game Bar in the Windows 10 Start Menu to configure custom keyboard shortcuts for turning your audio on and off and a whole lot more, while you are gaming.
