NCSKeys

NCSKeys is a command-line application that you can use to easily activate or deactivate the Num Lock, Caps Lock and Scroll Lock keys on your keyboard. It can be handled by all types of users with some minimal experience in console-based utilities.

Doesn't need setup

It's not necessary to go through an installation procedure since the key toggler is portable. It's wrapped in a single .exe file that can be run from any directory on the computer or a thumb drive. It doesn't change system registry settings or create extra files on the disk.
Double-clicking this file brings up a graphical window that shows the syntax. To use NCSKeys, you have to call its process from a Command Prompt window by specifying the file name and extension.

Enable or disable Num Lock, Caps Lock and Scroll Lock

The syntax is NCSKeys.exe [num | number] [cap | capital] [scr | scroll] [/e] [/d] [/t] [/? | /h], where you can ask the tool to take control over the Num Lock key (num or number), Caps Lock (cap or capital) or Scroll Lock (scr or scroll). It's possible to toggle just one of these keys, two or all three at the same time.

Toggle the key status from a Command Prompt dialog

You can instruct the software program to enable them (/e), disable them if they are already enabled (/d) or, if you don't know the current status, to change the current state by either enabling or disabling them (/t). The syntax can be brought up to the screen by typing /? or /h. No message is displayed on the screen once you hit Enter to execute a command.

Simple app for controlling Num Lock, Caps Lock and Scroll Lock

Although NCSKeys hasn't been updated for a long time, it worked smoothly on Windows 10 in our testing. It executed commands fast while remaining light on system resources consumption.
Taking everything into account, NCSKeys offers a quick and effective method for activating and deactivating the Num Lock, Caps Lock and Scroll Lock on your keyboard.
