It is easy to accidentally hit the Num Lock key or the Caps Lock key on a computer keyboard. Some keyboards even don't have lights to indicate whether these keys are on or off. This results in annoying input errors. The purpose of KeyStatus is to display the current status of the Num Lock key and/or the Caps Lock key in the notification area of the Windows taskbar. The program can also play a sound when the status of these keys changes.
KeyStatus is a 64-bit program for Windows. It has been tested on Windows 10 and 11.

Dark icons    Example with dark icons: Num Lock and Caps Lock on
Light icons    Example with light icons: Num Lock and Caps Lock off


KeyStatus_100_setup.exe installs the program for all users on a computer. Administrative rights are required for the installation. During installation, a shortcut in the Windows Autostart group is created for all users, or only for the current user.
In case the program icon is hidden after the first installation, click with the mouse at the up arrow in the Windows taskbar. Then a small window with icons will open. Use the mouse to drag the program icon from there to the notification area of the taskbar.
A new version of the program can simply be installed “over” the old version.



At the moment you can choose between German and English.

If you want to translate the program into another language, please use one of the files in the Lang subdirectory as a template and save your file there, too. The file format is UTF-8 with BOM. After a restart of the program this language will be available.
I would be glad if you send me your translated language file. I'll offer it for download on my website, and the next version of the program will automatically support this language.
