Windows 10: Cursor moves when it shouldn't

On my laptop with Windows 10, the cursor sometimes moves to the location of the mouse pointer. It behaves like I'm accidently hitting a hot key to cause the move. I've researched Windows 10 hotkeys, but can't find one that makes this move. The problem does not happen on my Windows 10 desktop, which has a separate keyboard. Why is this happening?

Windows 10 File Explorer - the cursor continually moves back to the top of the list

Original title: Windows 10 File Explorer

When scrolling through a list of files in Explorer, the cursor continually moves back to the top of the list. Also when I try to rename a file the cursor moves back to the top of the list during this process.

 

cursor dissappeared

Thank you both for your prompt replies, I tried all steps listed, some I had tries previously but I still tried them again, but still no cursor.

Do you have any other suggestions?

 

How to prevent the mouse cursor from moving up/down when scrolling on touchpad

Thanks for your reply.

Yes. There are a number of different cases. Take UWP application "Microsoft News" and traditional windows application Chrome browser as an example:

• If "Microsoft News" is of the focus, and if the mouse cursor is within "Microsoft News", when I scroll down using two fingers on touchpad, the mouse cursor first disappears and reappears to the bottom of the original position as a small dot, which also
  moves down on screen. After I stop scrolling, the small dot disappears, and the mouse cursor does not reappear, until I move the mouse on touchpad with a single finger.
• If "Microsoft News" is of the focus, but if the mouse cursor is within "Chrome" browser, when I scroll down using two fingers, "Chrome" browser becomes the focus (which should not have happened), and the mouse cursor completely disappears. It won't reappear
  immediately after I stop scrolling and move the mouse with a single finger, but reappear in one or two seconds from the neighborhood of where I would expect it to be. So in this case: 1. I won't expect "Chrome" becomes the focus but it will; and 2. I cannot
  predict precisely where the mouse cursor will reappear on the screen.
• If "Chrome" is of the focus, but if the mouse cursor is within "Microsoft News", the "Microsoft News" becomes the focus, which shouldn't have happened either. Then the mouse cursor becomes a small dot, which is the same as the first case.
• If "Chrome" is of the focus, and if the mouse cursor is within "Chrome" window, nothing suspicious happens.
• For the above four cases, if I scroll using a physical mouse rather than a touchpad, nothing suspicious happens.

This issue takes place every time when a UWP application and a traditional window application are both visible on screen.

More issues:

• When two UWP applications are both visible, if one scrolls (not tested with a mouse yet, only on touchpad) over the app not in focus, it becomes the focus, which shouldn't have happened.
• When two traditional windows applications are both visible, if one scrolls (not tested with a mouse yet, only on touchpad) over the application not in focus, the scrolling speed becomes
  very fast, even if the speed has been set to slow in the touchpad setting panel.

Probably there's no way but waiting for update. But if there's anything I can do to fix them, it would be of great help. Thanks again.

P.S. I'm using Samsung laptop preinstalled with Windows 10 Home edition. I never turn off Windows update.
