Configure Default Numlock Mode 0

Quick Overview:
The Numlock key on most standard keyboards toggles the numeric keypad between two different modes: (1) The Numeric Mode and (2) The Function Mode.

When the Numlock is turned "ON", the numeric keys on the keypad generate numbers, from 0 to 9. On the other hand, when Numlock is set to "OFF", these numeric keys generate other keystroke events such as "Home", "Page Up", "Page Down", etc...
Many versions of Windows by default, set Numlock key to "OFF", and this turns to be a bit annoying if you use that keypad regularly for numeric purposes. The good news is, you can always change this default behavior and set the Numlock key ON as default.
