I have XP, Windows 8, and Windows 10 machines inside Parallels on El Capitan. Each of the three Microsoft Windows Applications folders has multiple duplicate applications. For example CalendarIcon.exe [1] CalendarIcon.exe [2] CalendarIcon.exe [3] CalendarIcon.exe.app a lot of them include Icon or Shortcut in their name, but not all. For example: Google Chrome [1] Google Chrome [2] Can someone explain what causes this, and how to fix it?
