Disabling Num Lock key at windows startup

If the Num Lock key bothers you when you startup your PC, here is how to disable it.
Notice that you need to edit a registry value, so make sure you take a backup of your registry before changing any value.

Click Start –> Run > regedit :
Locate the key [HKEY_USERS\.DEFAULT\Control Panel\Keyboard], change the value of
[InitialKeyboardIndicators] from 2 to 0.

2 means that Num lock is turned ON at startup
1 means that Num lock is disabled
0 means that Num lock is turned OFF at startup
