Killkeys is a portable software program that can be configured by filling out the ini file of the same name. 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.

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.

The reason for using Sharp Keys instead of the Registry is simple. It’s faster, it offers a better overview and can be undone faster as well. With Sharp Key i was able to map the ESC key to the Caps Lock key which means that ESC is pressed when I press the Caps Lock key or ESC.

You can map other keys as well or disable them completely if you prefer that. Usage is pretty straightforward. Select a key that you want to map (From key) to another key from a list of possible keys (To key). In my case it was From Caps Lock to Escape. You can also map applications, functions (mute volume) or folders like the My Computer folder to keys.

Once you made all changes click on Write to Registry to make the changes in the Registry. The new settings will be available after a reboot or logout.
