Disable Computer Keyboard Keys

There are some keys on standard computer keyboards that you may not use at all, like the caps lock key for instance which can even have a negative impact on your activities on the computer when it is activated accidentally. The Windows key may be another example, as it can bring you back to the desktop when you are running full screen programs like games for instance, or the num lock key which enables or disables the numpad if available.

These keys can break your workflow when activated and you may find the idea attractive to disable them once and for all so that you can't activate them accidentally anymore.

Killkeys is a portable software program that can be configured for that task by editing an ini file that you can launch from the system tray or directly from the program directory. The ini file contains two important lines that define which computer keyboard keys are disabled. The first line is called Keys and will disable the key all the time while the name of the second is Keys_Fullscreen which will only disable keys when the computer is running a fullscreen application. You can for instance disable the Windows-key when you are running full screen applications, and keep it enabled otherwise.

The hex values of the keys have to be entered in the ini file. These hex values can be extracted from a Microsoft MSDN page easily.

Killkeys will use about five Megabytes of computer memory while running in the background. It will automatically place its icon in the Windows system tray with the possibility to hide that icon from there. The only way to kill the process then would be to kill it in the task manager or a similar computer program capable of displaying and killing processes.
