How do I disable the keyboard delay?

As far as I am aware you cannot completely remove the keyboard delay. The shortest delay you can set is "approximately 250 milliseconds".

To set the shortest delay possible:

1. "Start" > "Control Panel" > "Keyboard".

2. In the "Keyboard Properties" dialog select the "Speed" tab.

3. Set the "Repeat delay" to "Short" by dragging the slider to the right hand end.

   

4. Click "OK".

How can I set this value from a cmd shell?

Use the following command:

reg add "HKCU\Control Panel\Keyboard" /v KeyboardDelay /t REG_SZ /d "0" /f

The value "0" represents the shortest delay possible.

KeyboardDelay

Determines how long after a key is pressed and held down that the character begins to repeat. The values 0 (shortest delay; approximately 250 milliseconds) and 3 (longest delay; approximately 1 second) correspond to the four increments on the Repeat delay scale in Keyboard in Control Panel.
