Windows 10: What does holding fn + windows key do?

So I just recently realized that holding fn and pressing windows key disables my windows key, but what does it exactly do? Is there a way to disable this keyboard shortcut? Also, can I find this in settings?

FN key always on

If you press “Num Lock" (might also be labeled "Num Lk”) (I’ve also seen it labeled “Pad Lock” for numeric Pad) it turns on the blue keys, and inverts the meaning of the “Fn” key – it’s a way to use that embedded numeric keypad without having to hold down the “Fn” key the entire time. To fix it, just find and press the “Num Lock” or “Pad Lock” key again. (Note, sometimes these keys are themselves “Fn” keys, so you may, or may not, need to also hold down the “Fn” key to get the right function.) Often there is an indicator light associated with the setting.

Ummm, that is normal - depending on the function you are doing (assuming I understand what you are saying).

On a notebook, the Fn key is like a shift key that switches in a different set of functions for the F-Keys.

For example, in Windows pressing the F5 key typically refreshes the display. In File Explorer, it will refresh the displayed files. In a browser, it will refresh (reload) the webpage. But pressing Fn + F5 does something different, depending on your notebook. On my Toshiba notebook, if I hold down the Fn key and press F5, it switches the video output of my notebook between the notebook monitor, a connected external monitor, or both.

To clarify, I was saying "Accessibility" features maybe be controlled via the BIOS, not the Fn keys. And one of the Accessibility features makes the keys "sticky". This allows folks with some disabilities to press, for example, the Ctrl key, then the Alt key, and then Del in sequence instead of all at once. Same with the Fn key. The sticky feature would let you first press the Fn key, and then the F9 key (for example) and not Fn + F9 at the same time to enable/disable whatever Fn + F9 does with that notebook (it is the touchpad on my Toshiba).
