Num Lock on reboot - no way to get working

Hi

I have an E5-571-371W

I cannot get the Num Lock to remain ON and activated on start up, whether from log out/lock or reboot from sleep.

I have tried:

Changing the registry for default and current user to 2 for keyboard

Turning off Fast Start up

Disabling Launch Manager

and none of these has worked.

This is really really annoying as i use my numberpad heaps.

Any ideas?

I have Windows 10.
