After a re-install, the taskbar icon is left in a bad state. The old desktop icon is still on the desktop. Attempt to pin that icon does not update the taskbar. I have to go into the windows menu, into the viewer folder, drag the icon to the desktop, until the old icon, and pin the new icon. The installation needs some work.
I have not used that procedure. But nearly every time I've updated I've been left with this scenario. I did not do an unistall, I allowed the installation to replace the current version. Windows 10, fairly fresh install.
