Caveat: the solution in this answer does not solve the problem, it just makes the symptom go away. If you don't like the approaches using the Group Editor or changing settings, or if those approaches don't completely make the problem disapper, you can try my hack:
I created a new task using Task Schedulertask scheduler. It runs this script, which I call cleanup_evtx.bat:
del c:\windows\temp\AppXDeploymentServer_*.evtx c:\windows\temp\AppXPackaging_*.evtxFWIW I believe that the Hex code that follows the AppXDeploymentServer_ is always the same. Someone could probably map that to the specific Windows Store app causing the problem. I could not find the answer to that part of the puzzle, thus the hack above.
