How to Change FN Key Settings in Windows 11: A Step-by-Step Guide

Changing the function key settings on a Windows 11 computer can enhance your user experience and make it easier to access certain features. This task involves accessing the BIOS or UEFI settings during startup and adjusting the function key behavior. Once you’ve made the desired changes, your function keys will either perform their standard duties or the special functions labeled on the keys, depending on your preference.

Step by Step Tutorial to Change FN Key Settings Windows 11

Before diving into the steps, it’s important to know that altering the function key settings can modify how you interact with your computer. By following these steps, you’ll be able to choose whether your function keys act as standard function keys or as multimedia keys.

Step 1: Restart Your Computer

Restart your computer and as it’s booting up, press the necessary key to enter the BIOS/UEFI settings.

The key you’ll need to press varies depending on your computer’s manufacturer. It’s often F2, F10, Del, or Esc. Keep an eye out for a prompt on the startup screen that tells you which key to press.

Step 2: Navigate to the Function Key Behavior Setting

Once in the BIOS/UEFI menu, look for an option related to the function keys. This might be under a ‘System Configuration’ or ‘Advanced’ tab.

The exact wording will differ between computers, but you’ll want to find an option that mentions ‘Function Key Behavior,’ ‘Action Keys Mode,’ or something similar.

Step 3: Change the Function Key Setting

Select the setting and choose the option that suits your needs – either ‘Function keys’ or ‘Multimedia keys.’

If you choose ‘Function keys,’ your F1-F12 keys will perform their standard functions. If you choose ‘Multimedia keys,’ they’ll perform the special functions labeled on the keys, like adjusting volume or screen brightness.

Step 4: Save and Exit the BIOS/UEFI

After making your choice, save the changes and exit the BIOS/UEFI setup.

Be sure to find and select the ‘Save and Exit’ option, which will typically prompt you to confirm your choice. Once confirmed, your computer will continue booting up with the new settings applied.

After completing these steps, you’ll notice the behavior of your function keys will have changed according to your preference. This allows for a more personalized and efficient use of your keyboard, especially if you frequently rely on the special functions.

Tips for Changing FN Key Settings Windows 11

  • Always check your computer’s manual or manufacturer’s website for specific instructions related to your model.

  • Remember that changing the function key behavior might require you to use the ‘Fn’ key to access certain functions that you were previously able to access directly.
  • If you change your mind, you can always repeat the steps to toggle the function key settings.
