It can get annoying if you have to constantly and consistently press the FN key to use the F1-F12 keys on your keyboard. Luckily, there are a few ways you can change that. This wikiHow article will teach you how to use the function keys (F1-F12) without pressing the FN key on Windows 10. Beware that some computer manufacturers have it set up already to set your FN key to activate the small icon on the F1-12 row instead of the F1-12 keys; check your computer manual or test the keys to see if the FN key is necessary before you continue.

Making F Keys Work without Fn

Use the Fn Lock feature to use function keys without the Fn Key. Find the Fn Lock key on your keyboard—it may say FnLk or have a lock icon. Hold down the Fn key and press Fn Lock. Release your fingers and use the function keys as normal.

- For example, if you're using a Lenovo ThinkPad, the Esc key says "FnLk" at the bottom, which means that you'll use the Esc key as the function lock key.^{[1]

Enter the system BIOS or UEFI. Depending on your computer manufacturer and BIOS version, you may be able to change the behavior of the function keys in the BIOS. Start by booting into the BIOS. The standard way to do this is to reboot your PC and press the required key (usually F1, F2, F10, or Del). However, most modern Windows 10 PCs now have an easier way to do this:^{[3]
