Right click on the desktop and select Personalise. You will see Taskbar listed at the bottom of the menu. See what you can do in there to remove the icon.
I just saw it there so I couldn’t blame it on something specific. I’ve disabled everything in Startup in Task Manager and it’s still there. It’s hidden in Administrator account. Given up. Thanks for your interestDid you install something just before you noticed the icon?
You could check in Task Manager (control, alt, delete) and check Start-up. The process must be starting when Windows boots up.
Other than that I'm stumped too.
