So I do much tweaking lately and running across errors like Store-related 800706d9 error that prevents me from download any Store App or updating it. I researched and it is supposedly Firewall-related, but my Firewall was running and I used Defaults, but that did not work. Event Log is miserable and doesn't tell you squat! Are there no better debuggers-error recorders that would point me closer to where the issue is???
