To verify the function keys lock status on Windows 10/11, you can check if the Fn keys are working properly. Press the “Fn” key along with another key that has a function assigned to it, such as brightness or volume control. If the function is activated, then the Fn keys are working. You can also check the lock status by looking for an indicator light on your keyboard that shows when the Fn keys are locked. If the indicator light is on, then the Fn keys are locked.
