How to Change Fn Key Settings on Windows 10 and 11

Function keys (F1–F12) on your keyboard can serve as shortcut keys for various system functions like adjusting volume, brightness, and playback, in addition to their standard functions. Many users wish to customize or modify these keys to suit their needs better, which often involves the need to change Fn key settings. In this guide, we’ll learn how to change Fn key settings on Windows 10 and 11, including how to lock the Fn key, turn it off, and adjust other settings for an improved user experience.

Why Change Fn Key Settings?

Changing your Fn key settings can streamline your keyboard functions, eliminating the need to press the Fn key each time you want to perform a standard function or system shortcut. Whether you want the function keys to act as dedicated media controls or prefer to use them for tasks like refreshing your browser or opening Help, changing these settings can optimize your workflow and make your device more user-friendly.

Methods to Change Fn Key Settings on Windows 10 and 11

There are several ways to change Fn key settings depending on your device model and keyboard type. We’ll explore the most common methods below:

1. Change Fn Key Settings Through BIOS/UEFI

One of the primary ways to adjust Fn key settings is through your device’s BIOS or UEFI menu. This method works well on most laptops and desktops with Fn keys.

1. Restart Your Computer: To access BIOS/UEFI, restart your computer and repeatedly press the BIOS key (typically F2, F10, DEL, or ESC) as your computer starts. The correct key may vary depending on your device’s manufacturer.

2. Enter the BIOS/UEFI Menu: Once in the BIOS menu, use your keyboard’s arrow keys to navigate to a section labeled “System Configuration” or “Advanced Settings.”

3. Locate Function Key Behavior Settings: Look for an option like “Action Keys Mode,” “Function Key Mode,” or “Function Key Behavior.” This setting often determines whether the function keys require pressing the Fn key for standard F1–F12 functions or shortcut commands.

4. Multimedia Key Mode for standard functions on most keyboards:

Key (F1–F12) Mode	Function Key Mode	Multimedia Key Mode
F1	Opens Help in many applications	Mutes sound
F2	Renames selected file or folder	Lowers screen brightness
F3	Opens search feature in Windows/File Explorer	Increases screen brightness
F4	Places cursor in the address bar in browsers	Previous track (media playback)
F5	Refreshes page or window	Play/Pause media
F6	Moves cursor to address bar in browsers	Next track (media playback)
F7	Activates spell check in some programs	Lowers volume
F8	Accesses boot menu on startup Increases	volume
F9	Refreshes document in Microsoft Word	Opens email client (or assigned function)
F10	Activates menu bar options	Open web browser (or assigned function)
F11	Enters/exits full-screen mode	Reduces backlight brightness
F12	Opens developer tools in browsers	Increases backlight brightness

In Function Key Mode, the keys perform traditional tasks such as refreshing the page (F5) or renaming a file (F2). In Multimedia Key Mode, these duplicate keys perform quick-access multimedia functions like adjusting volume, controlling playback, and modifying screen brightness.

5. Save Changes and Exit: After adjusting the settings, press F10 (or the designated save key) to save the changes and restart your computer.

Note: BIOS/UEFI menus vary between manufacturers. If you’re unsure of the exact steps for your device, consult your manufacturer’s website or device manual.

2. Use Manufacturer-Specific Software

Some manufacturers include software allowing users to change function key settings directly from Windows 10 or 11. Here’s how to access these settings for various brands:

a. HP Laptops

HP laptops often feature the HP System Event Utility or HP Support Assistant, which includes keyboard customization options:

– Open the HP Support Assistant or download it from HP’s website.
– Find the Keyboard or Function Key settings section.
– Choose between Action Key mode (for multimedia shortcuts) or Function Key (for standard function tasks).

b. Dell Laptops

Dell provides the Dell QuickSet utility that allows for quick customization of function keys:

– Open Dell QuickSet from the Start menu.
– Navigate to Function Key Behavior settings.
– Select your preferred settings, such as Multimedia or Function Key modes.

c. Lenovo Laptops

Lenovo laptops come with Lenovo Vantage software, allowing you to adjust function key settings:

– Open Lenovo Vantage from your Start menu or download it from Lenovo’s support page.
– Go to Device → Input & Accessories.
– Select Function Key or Multimedia Key mode in the Function Key section.

For other manufacturers like ASUS, Acer, or MSI, visit the support page of the respective brand to find software that can modify Fn critical behavior on your device.

3. Use Windows Mobility Center to Adjust Function Keys

On some laptops, the Windows Mobility Center can adjust Fn key settings. Here’s how:

1. Open Windows Mobility Center by pressing Win + X and selecting it from the menu.
2. Look for a section labeled Function Key Behavior or similar.
3. Choose the preferred mode, Function Key or Multimedia Key mode.

Note: Not all devices include Fn critical settings in the Windows Mobility Center. This option depends on your device’s manufacturer, so if you don’t see this option, try one of the other methods.

How to Lock or Turn Off the Fn Key

Many users prefer to lock or turn off the Fn key to avoid needing to press it in combination with other function keys. Below are several methods to lock or turn off the Fn key on your device.

1. Use Fn Lock to Lock the Fn Key

Most keyboards feature an Fn Lock key, often integrated with the Esc key or a function key, such as Caps Lock. Here’s how to enable Fn Lock:

– Hold down the Fn key and press the Fn Lock key (often Esc or Caps Lock).
– Release both keys. You should now be able to use function keys without pressing Fn.

To unlock, repeat the same key combination.

2. Disable the Fn Key in BIOS/UEFI

If you want to disable or modify the Fn essential function permanently, you can do so in the BIOS/UEFI settings:

1. Restart your computer and press the designated BIOS/UEFI access key (often F2, F10, DEL, or ESC).
2. go to Advanced Settings or System Configuration in the BIOS menu.
3. Locate the Function Key Behavior or similar setting and select Function Key Only or Disabled to turn off the Fn key.
4. Save changes and restart your computer.

3. Use Third-Party Software to Disable or Customize Fn Key Settings

Consider using third-party tools like SharpKeys or AutoHotkey for additional customization options. These programs allow you to remap keys on your keyboard or assign specific functions to the Fn key.

1. SharpKeys: This program allows you to remap keys. For example, you can remap the Fn key to another key or turn it off altogether.
2. AutoHotkey: This program enables more advanced key customization and scripting. You can create a custom script to turn off the Fn key or change its behavior as desired.

Additional Tips for Changing Function Key Settings

1. Experiment with Key Combinations: Some laptops allow users to quickly change function key settings by pressing Fn + F3 or Fn + F12 to toggle between function fundamental modes.

2. Check Your Device Manual: If you encounter issues while modifying Fn key settings, refer to your device’s manual or the manufacturer’s support page for guidance specific to your model.

3. Use On-Screen Keyboard: After modifying your settings, test them using the On-Screen Keyboard. This tool is accessible by typing “On-Screen Keyboard” into the Start menu search bar.

4. Try Windows Updates: Sometimes, Windows updates include keyboard or driver updates that can impact the behavior of function keys. Make sure your device is up to date by checking Windows Update settings.
