Solved Answer
Personal computers (PCs) do not have the so-called Function (FN). Thus, if you are a PC owner and have nothing in common with the FN key, please bypass this post. Otherwise, you may found useful information on how to fix Function keys not working issue on Windows 10.[1]
Fn keys have been designed to perform specific actions on laptops, for example, turn Wi-Fi[2] off or on, change screen’s brightness, turn the sounds on or off, get the screen to sleep, and so on. The Fn key always goes in combination with the other keys, usually F(1-12).
Unfortunately, quite frequently the Fn key stops working and this typically happens after upgrading Windows from earlier versions or installing the latest updates. According to the latest reports, people using ASUS, HP, Acer, and Lenovo[3] laptops most frequently encounter issues related to Fn keys.
