Yesterday I installed JRiver Media Center 23 shortly before supper, and played some music. When I returned to my computer after supper I found that my Start Menu would not open, and the right-click menu on Taskbar buttons did not work.
It was not my first experience with this problem. It happened about a month earlier, when I upgraded to Media Center 23, but on that occasion some time had elapsed between the installation and the Start Menu/Taskbar problems. Although I mentally noted the association of the problem with installing Media Center, I frankly trusted that JRiver would be sufficiently knowledgeable about Windows 10 by now that they wouldn’t release an incompatible product. So I put that out of my mind, and spent days researching and trying various proposed solutions to the problem, unsuccessfully. I finally gave up and completely reinstalled Windows 10. And then spent many more days installing and configuring my applications.
My system was rock-solid until I reinstalled Media Center 23 yesterday. This time, I remembered the association. And so to address the problem I tried uninstalling Media Center.
Problem solved. Start Menu and Taskbar working fine.
I’ve been a user of Media Center since 2004. No longer.
