That's interesting. I always thought it would only need to exist in RAM because the Num Lock state doesn't persist between reboots.

Maybe I'm confusing this with another OS which did store it persistently?

I know in the BIOS you can usually specify the Num Lock status at boot but I'm not sure if it's effectively Yes/No or Yes/last state remembered by Windows. I'll experiment and see how it works on my PC.

On my parent's Windows 10 laptops the state of NumLock is surely persisted between reboots (and after a full power down). I doubt it's the laptop/external keyboard itself that is doing that, but maybe it is.

Because Caps Lock and Scroll Lock are not persisted (it doesn't make much sense to persist them from usability point of view).
