How to turn NUM LOCK off for the logon screen

When I use a laptop running windows XP, I really want to turn the NUM LOCK off for the logon sreen. To turn NUM LOCK off before a user logs on, I use the steps below:

1.	Run Registry Editor (Regedit.exe).
2.	Navigate to HKEY_USERS\.Default\Control Panel\Keyboard.
3.	Change the value for InitialKeyboardIndicators from 2 to 0.

If a desktop keyboard or a numeric keypad is present, I will try to keep the value 2. The method is borrowed from MS KB154529.
