Fields

Default Startup File Use this field to specify a data file that should be loaded by default, when Family Historian starts up.
Register as default application for GEDCOM files If checked, Family Historian will automatically re-register itself, whenever it starts up, as the default application to use when opening GEDCOM files. Being the default application means that if you double-click on a GEDCOM file, Family Historian will be opened to load it. You are recommended to leave this option checked, unless you have some specific reason to do otherwise.
Display the Records Window, instead of the Focus Window, at Startup Self-explanatory
Check for Updates Automatically Get Family Historian to periodically check for new updates.
