CapsLockON

Many laptop models, and even some keyboards, are not equipped with status indicators for the Caps Lock and Num Lock keys. Presumably for lack of space, but some users simply can’t do without them.
CapsLockON is a basic application that can display the current status of these keys in the system tray. It is very lightweight and requires no installation, but the tray indicator isn’t exactly stylish.

Just download the app and you’re good to go

This program comes in the form of a single executable file, and you don’t need to go through an installation process before running it. It is, therefore, very easy to deploy, though this shouldn’t be surprising when dealing with such a simple app.
Since the program doesn’t store any data on your PC, you don’t have to worry about any traces being left behind if you decide to delete it.

Check Caps Lock and Num Lock status from the system tray

You get all the information you need by just glancing at the application’s tray icon; the name of each key is displayed in white if it is active, and red if it is inactive. However, it has to be said that the icon’s design leaves a lot to be desired.
Scroll Lock status is not tracked, but very few people use this mode nowadays, and the key has even been removed altogether by various manufacturers.

Great for laptop users, but its design is a bit too rudimentary

On the whole, CapsLockON does what it’s supposed to, but it is not the best choice for users who like to keep their desktop looking modern and stylish. If the icon were redesigned, or if some more alternatives were provided, this application would be much easier to recommend.
Nevertheless, we have to appreciate the program’s lightweight design, as well as the fact that it does not need to be installed on your PC before use.
