Step 1: Automatically Update the Keyboard Drivers
If the function keys on your Windows 10 PC keyboard aren't working, it's possible that the keyboard drivers are to blame. When your system experiences a device driver-related issue, the best way to resolve it is to use the best driver updater tool.
A driver updater tool can instantly update your system's defective, damaged, or missing drivers by downloading the most recent versions and installing them on your system.
All you have to do is download a free driver updater tool, such as Bit Driver Updater, and run a scan with it. Once the defective keyboard driver has been identified, click the update button to have the tool download and install the latest version of the keyboard driver. The steps are outlined below.
- To begin, click the button below Windows-Download to download and install the Bit Driver Updater tool.
- Then, click the ‘Scan Drivers' button to see if your PC has any faulty, missing, or outdated drivers.
- Select the ‘Update Now' button next to the flagged keyboard device to have the latest driver version downloaded and installed automatically.
Step 2: Try the Hardware Troubleshooter
If the keyboard shortcuts aren't working, use the built-in hardware troubleshooter to resolve the problem. The main function of the troubleshooter is to restart the impacted devices (broken by Windows Updates), such as the keyboard, as well as their services. To run the hardware troubleshooter, follow the steps below:
- Go to the Settings app on your Windows 10 computer.
- Then go to the section Update & Security.
- On the left side panel, select the Troubleshoot option.
- You must also expand Hardware and Devices by clicking on it.
- Finally, press the "Run the troubleshooter" button and wait for the troubleshooter to identify and correct any issues.
When the process is complete, check to see if the function keys are now functional. If that doesn't work, try the fixes below.
Step 3: Uninstall the System Hotkey Drivers
Uninstalling the hotkey drivers from your laptop is one way to fix the function keys not working on Windows 10 issue.
- Locate the hotkey drivers using the Device Manager app.
- Then, from the context menu, right-click on the hotkey driver and select Uninstall.
- Find and uninstall the HID-Compliant Keyboard and HID-Compliant Mouse drivers as well.
Finally, restart your computer and check to see if the function keys now work.
Step 4: Uninstall the Synaptics Pointing Device Driver
Because of the Synaptics Pointing Device driver, you may occasionally experience Fn keys not working.
So, uninstall it and see if you can use the function keys normally after that. The Synaptics Pointing Device driver can be uninstalled from Device Manager.
Step 5: Disable Filter Keys
If you've tried everything and still can't get the function keys to work, there's one more thing you can try. The filter keys must be turned off. Filter keys can be used to prevent keystrokes from being repeated. Disabling it can be useful because it can sometimes block the function keys on your keyboard.
Go to the Control Panel tab.
The Ease of Access Center will be launched.
Select the option to "Make the keyboard easier to use."
Uncheck the “Turn on Filter Keys” box in the Filter keys option.
To finalize the changes, click Apply and OK.
