So the registry database of this operating system contains the configuration for touch operations for Windows as well. Consider the scenario; you’re using a touch operated Windows 10/8 system. After you log in, the mouse pointer disappears, and it practically behaves like arrow keys.
From this Microsoft Community thread, it is worth noticing that this appears to be occurring on touchpads, while the external mouse connected to the system works fine. If you too are facing trouble with this, you might have observed that it is like the very opposite of mouse keys, that is, you can control arrow keys using the touchpad. Now let us try to inspect what happens to cause this, as I said before the issue is only with touchpad, so we should check out the touch operation configuration entries in the registry.
