Can't change screen brightness? If the Function key for Brightness is not working in Windows 11/10, the problem may be with drivers. This post will help you fix the issue.

The Fn key is also known as the function key, and on Windows and most Mac keyboards, you'll find it located in the bottom-left corner of your keyboard.

Similar to Shift, Ctrl, and Alt on Windows and Command on Mac, the Fn is a modifier key, meaning it is used in combination with other keys to change their usual function.

If Left Alt key and Windows key are swapped on Windows 11/10, check which type of keyboard you are using. Use these solutions to fix this.
