Recently upgraded from Windows 8 Pro to Windows 8.1 Pro. After unpinning the Windows Store App from the taskbar and restarting or logging out/logging in, it reappears time and time again no matter what I try. The app reppears in the taskbar regardless of whether or not I have the "Show Store apps on the taskbar" checked in the taskbar's properties.

I thought for a second that this could be because I am using the built-in administrator account--since metro apps seem to be weird about that. So I tried creating a guest account and unpinning the store app. Unfortunately after signing off and back on again the app was still not gone. Searched google and eightforums many times to see if anyone had the same problems, but I found nothing.
