How do I turn off the NUM LOCK key at startup?

There is not an option in the Windows control panel to make the NUM LOCK key not activate at startup,

you will need to go under the hood for a few seconds and do some registry editing.

Open regedit by going to the Start Menu, clicking Run, and then typing in regedit.

Browse to HKEY_USERS\.Default\Control Panel\Keyboard

Modify the string called InitialKeyboardIndicators, change it from 2 to 0.

Close the editor, and you’re done.

Making sure that the NUM LOCK key doesn’t enable itself at startup is.
