Physically remove the key. Pry the Caps Lock key from the keyboard. This will leave a hole where the key used to be, but you don't need administrator privileges to do this.

Run the program. After installing KeyTweak, open the program. You will see a display of a virtual keyboard. The keys will be numbered instead of displaying the characters normally printed on them.

Select the CapsLock key from the diagram. You can ensure you have the right key selected by looking at the Keyboard Controls section. There you will see what function is currently assigned to the selected key.

Click "Disable Key". This button is located in the Keyboard Controls section. This will turn off the selected key, which will keep Caps Lock from activating when you press it.

Reboot your computer. In order for the changes to take effect, you will need to reboot your computer.

Turn Caps Lock back on. When you want to re-enable the CapsLock key again, open up KeyTweak, select the CapsLock key from the diagram, and click the Restore Default button in the Keyboard Controls section. You will need to restart your computer for the changes to take effect.
