To start or stop a recording of the game that you’re currently playing, press Win + Alt + R. If all you want to do is start or stop a recording, for example, you can activate it using a keyboard shortcut. Just because the Game Bar doesn’t pop up when you use its shortcut in certain games, doesn’t mean that it isn’t actually working. You also generally can’t make use of HDR modes when using a borderless window. Just be aware that running some games in a borderless window can have a negative effect on performance.
