How to Disable FN Key on Windows 11: A Step-by-Step Guide

Disabling the Fn (Function) key on Windows 11 can make your keyboard shortcuts easier to use. To do this, you can change settings either through your computer’s BIOS or UEFI menu or directly within Windows. Follow these simple steps to disable the Fn key.

How to Disable the Fn Key on Windows 11

This guide will walk you through the necessary steps to disable the Fn key on a Windows 11 computer. By following these steps, you’ll be able to use your function keys without having to press the Fn key.

Step 1: Access BIOS or UEFI Settings

First, restart your computer and access the BIOS or UEFI settings by pressing a specific key (usually F2, Delete, or Esc).

The exact key you need to press can vary depending on your computer’s manufacturer. Check your computer’s manual or look up the specific key for your model online.

Step 2: Navigate to the Advanced Tab

Once you’re in the BIOS or UEFI menu, use the arrow keys to navigate to the Advanced tab.

The Advanced tab is where you’ll find settings for your keyboard, including options to change how the Fn key operates.

Step 3: Find the Function Key Behavior Option

Look for an option called Function Key Behavior or something similar.

This option controls whether you need to press the Fn key to use the function keys (F1, F2, etc.) as standard function keys or for their special functions (volume control, brightness, etc.).

Step 4: Change the Setting to Multimedia Keys

Select the Function Key Behavior option and set it to “Multimedia Key First” or “Function Key First,” depending on your preference.

By setting it to “Multimedia Key First,” the function keys will perform their special functions without needing the Fn key. If you prefer the opposite, set it to “Function Key First.”

Step 5: Save and Exit

Finally, save your changes and exit the BIOS or UEFI menu.

Usually, you can do this by pressing F10, but the exact key might differ. Be sure to confirm any prompts to save your changes.

Now, when you use your function keys, you won’t need to press the Fn key.
