Windows 10: Cursor randomly jumps to start button and opens the start menu

My cursor keeps jumping to the start button and opening the menu. It happens randomly every 15 minutes or so. Not a big deal but it's frustrating and disruptive to my work - especially when I end up inadvertently clicking on an app that I didn't mean to open. The touchpad works completely fine otherwise.System InformationOS Name: MS window 10 homeVersion: 10.0.19045 Build 19045System Model: HP Laptop 15-db0xxxSystem Type: x64 based PCProcessor: AMD Ryzen 5 2500UPointing Device: Synaptics SMBus TouchPad I found a couple similar complaints that were not resolved:https://answers.microsoft.com/en-

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?

 

Start menu not working

I found the following article, ran the suggested powershell command and my start menu is working again. Here it is as I found it:
Go to Start menu button and right click on it. This will open the contextual menu, after which you need to select Command Prompt (Admin). Once Command Prompt is open, go ahead with the following steps.

• Type and enter: Powershell
• Type the following: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
