Windows 10: the mouse on my screen moves when I press arrow keys

the mouse on my screen moves when I press arrow keys, yet the mouse control with the key pad is turned off. this is very inconvenient and I don't like it. how to fix it?

again, the function to control the mouse with keys is turned OFF. this is awful. how do I fix it?

Mouse pointer moving on arrow keys pressed

I'm encountering a strange problem on my W10 computer, for a few days my arrow keys have been "driving" my mouse pointer. Pressing the left arrow key will move the pointer a few pixels left, etc.

The first thing that came to my mind was "oh well, I must have enabled Mouse Keys inadvertently". But Mouse Keys use the numpad and even then, it's not enabled. Rebooting doesn't help, but I've noticed it doesn't happen if the current window is ran as another user (Administrator) or if it's the Task Manager, which suggests the event filter that's catching the key press events is only active on my UID.

I've tried killing various processes but I'm running out of ideas. I'm fairly sure it's a dumb issue but it's been driving me nuts.

 

Cursor moves when pressing direction keys

Try turning scroll lock to ‘On’.

Press the Windows key on your keyboard & in the box that appears, type Ease of Access mouse settings and press enter.

In the Mouse Keys section, toggle the switch under ‘Use numeric pad to move mouse around the screen’ to ‘Off’.

Press Alt+F4 to exit this menu.

Or:

Press Windows Key + R to open the Run box & type ms-settings: and press enter.

In your Settings window, the text cursor is already in the search box. Type "mouse keys." Press the down arrow on your keyboard to select the first suggestion, ‘Control the mouse pointer with the keyboard’.

Click enter & The Ease of Use settings for your mouse is opened, then to turn off Mouse Keys to use the numeric keypad to move the mouse pointer. Press Space to toggle the button to the off.

 

Arrow keys moving mouse cursor

My keyboard is moving my mouse cursor again, from the arrow keys. I checked in the settings and turned off, again, the setting that makes the num keys move the mouse, but the arrow keys are still doing it. I just want to turn this off. this is not
the first time it has happened and I can never remember how I managed to make it stop the previous times. I do remember that sometimes it just stops after i mess around for 2 hours trying to make it stop, or by unplugging and replugging my mouse. I just want
it to stop.
