Thanks for your reply and opinion. I don´t think so because i made a fresh install of Win10 and have nothing else installed than OldNewExplorer 1.1.9 and StartIsBack 2.8.9 at the moment to find my way through this awful looking OS. So it can only be the new build of Win10 that is reverting back to default if you ask me. I hope that Tihiy can confirm or deny my experience.
