FSX keeps important controls and configuration files in places that are not always obvious, particularly on Windows 10 and 11. These answers locate FSX.cfg for boxed and Steam installations, explain how to back it up before editing, restore a missing menu bar and clarify what ResetXDirectorySecurity.exe changes when folder permissions have gone wrong.
Coverage also includes setting up FSUIPC for controller assignments, calibration and add-ons that depend on it. Fly Away team guidance is written and tested to distinguish safe configuration work from unnecessary tweaks, with attention to hidden AppData folders, administrator rights, conflicting control mappings and the differences between FSX installation paths.
