Apart from closing the currently active windows, the Alt F4 combo also helps you shut down, hibernate, sleep or sign out of your computer.

Continue reading to know how to fix the Alt F4 not working problem in Windows 10.

What do I do if Alt F4 is not working in Windows 10?

1. Check FN Lock 

If the Alt F4 key is not working on a Windows 10 laptop, check if it requires an FN key to activate the combo. The Function keys in a laptop usually serve multiple purposes, such as working as multimedia keys by default. To activate the function keys, laptops come with a dedicated Fn key that unlocks the function properties. For example, instead of pressing the Alt + F4 key directly, press and hold the Fn key on your keyboard, and press the Alt + F4 key. This should either close the currently active window or bring up the Windows shutdown settings. This is a simple solution, but it might help if Alt + F4 is not working on your PC.

2. Update keyboard drivers 

Outdated or corrupted keyboard drivers can affect your input functions. To fix the issue, make sure you have the latest keyboard drivers installed. While you can update the keyboard drivers manually, driver updater utilities are by far a better solution. These types of utilities will find and update both missing and outdated drivers on your Windows PC. There are a plethora of programming tools accessible online that can successfully update all of your PC keyboard drivers. First and foremost, install a driver downloader such as DriverFix on your computer and check in the utility menu for new updates. The software identifies your keyboard and searches its database for important updates. The program will later supply upon the detection of the most recent driver. It is the quickest and easiest technique for updating your keyboard drivers. SPONSORED ⇒ Get DriverFix

3. Turn off Sticky Keys 

Sticky Keys helps differently-abled people to access their computer. When enabled, it will allow a key to be activated even after it is released. While it is an excellent feature, having it enabled can prevent the user from using keyboard shortcuts to carry out some actions.

4. Run keyboard troubleshooter

After running the troubleshooter, check if Alt + F4 is still not working on your PC.

5. Disable Legacy Fx function in BIOS

After the restart, check if you can use the Alt F4 key on your keyboard to close apps and access the shutdown menu. If the issue persists, modify some registry entries to resolve the issue. Alternatively, change function keys in Windows 10 to bind your F4 key to another key.

6. Modify Windows Registry settings 

Exit Registry Editor and check if you can use the Alt+ F4 shortcut on Windows 10.

7. Check for hardware issues 

Even if the issue persists after following all the troubleshooting steps, it is time to diagnose your keyboard for hardware issues. Laptop and external keyboards over time can wear off and may require replacement. While you can use an external keyboard, this may not be ideal for those who use their laptop on the go or carry it out. Contact your laptop service center for a better diagnostic of your computer keyboard. The Alt F4 not working issue in Windows 10 usually occurs due to Fn lock being enabled.
