Windows 10: Frustrated with Ctrl + Mouse movement jumping to start button

I don't know what to do to fix this. I use the Left Ctrl button my computer to select multiple files at the same time ie., emails, files, folders, etc, but with my new Windows 10 computer any movement of the mouse paired with holding down the left ctrl button and only the left one weirdly makes the cursor jump to the start button. It's really annoying and I can't find any way to fix this. The computer is brand new so it's not likely a virus or anything. It seems like an accessibility feature but I can't find any way to turn it off. Does anyone have any suggestions??

:)

 

Weird mouse movement (jumping and circle seen)

Hello

• Are referring to an external mouse or the laptop touchpad?
• Have you tried using an external mouse and check if the issue persists?

  winver, and then press
  Enter.

Jump lists do not show on taskbar but do on Start button


I want jump lists on both taskbar and Start button, they are only showing on Start button. I have checked the registry key that controls this attribute and the value is "1" so both should show. The "Show recently opened items... " switch in Settings is set to ON. Something is supressing the jump lists on my Taskbar icons. I do get live thumbnails on the icons but that is all. Right clicking does nothing.

Windows 10 Pro is an upgrade install and did not clean install afterwards. In my opinion not needed. I have run SFC /scannow and got a clean report.

CORRECTION: The Start button is showing the context menu on right click, not the jump list, unless that IS the jump list.

Is the registry key value 1 to show the jump lists?

 

Can't unpin dead link to D:\ from File Explorer - Taskbar & Start Menu

Mouse buttons haven't been reversed, and they work fine in all other contexts (including other items on this very same pinned list in File Explorer).

Also want to add:

I've attempted all the methods of unpinning that are listed in this tutorial:
