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
