Windows 10: Cursor keeps jumping to start button and opening the start menu

Since I bought this laptop the cursor keeps jumping to the start button and opening the start menu. It's really frustrating. It does it about every half hour or so. I looked at a few threads on here and Reddit but nothing has worked. My laptop doesn't have a touch screen and I don't use a wireless mouse, just the trackpad.

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?

 

My cursor keeps jumping and opens the Start Menu every 3 to 5 seconds

My cursor keeps constantly jumping to the Windows start button and then opens up the full start menu. This happens every 3 to 5 seconds , interrupting whatever you are doing eg. only allowing up to 4 or 5 words typing or viewing of any wind .

I have moved to Windows 10 for nearly 10 months now and it is so troublesome compared with 7. I have run all the scans and checks and even Bullguards help could not solve. I have an all in one desktop Lenovo with Bluetooth devices which is still modern enough
for my uses.

I have limited knowledge and would greatly appreciate any help as I have a big project to complete . Thank you.

This seems to be a problem since fall update that for me happens when I am in a legacy win32 application and try to select something - cursor jumps to start button or Cortana EVERY time. I do not have a touchscreen.
