Is it possible to have Num Lock ALWAYS ON, without the ability of the Num Lock key to turn off?

Solution 1:

I use CapShift and it's free:

"CAPshift extends the Caps Lock key by slowing it down...

  • Hold down for 0.5 sec to enable/disable.
  • Hold down for 1 sec to show the menu.
  • Rightclick the tray icon to show the menu.
  • Also slows down F1, Insert, NumLock and ScrollLock."

The Advantage is: You don't lose the ability to change NumLock if you really need to.

Solution 2:

Physically remove the NumLock key. When your finger goes to press it, it won't be there.
