📝 Notes

KeePassXC stores all substantive settings in INI files at %APPDATA%\KeePassXC\ — the registry is used primarily for installation metadata and file associations.
The .kdbx format is also used by KeePass 2; both apps may compete for the file association.
The browser integration (KeePassXC-Browser) extension communicates via a named pipe; no additional registry keys needed.
