Okay...so I figured it out. Jriver media causes this. I used to use itunes for my music, but switched to jriver media (much better than itunes!!!). It has something to do with shell integration. Now you can turn this feature off in jriver, but the problem still persists. The mere fact that it is even installed (doesn't need to be running) still produces the problem, it just takes longer when not running. It screws with everything in the app container, specifically shellexperiencehost.exe. So I set a watch dog to terminate this. Now this process controls your start menu operation and right clicks on pinned programs in the taskbar (so no jump lists or start menu). Well that sucks. I went to jriver media forums, and a lot folks have the same problem. According to the devs there it is a windows 10 problem...so wait windows 10 is broke and not your software? So I installed as a different media program on my laptop..I installed foobar..guess what..the same thing happened then too! Itunes, it works fine.So it does look like a windows 10 problem. In the mean time I have installed start10 to get around this.
