📝 Notes

Flameshot uses Qt's QSettings which maps to HKCU\SOFTWARE\flameshot-org\flameshot on Windows.
The startup entry is only created when "Launch at startup" is enabled in preferences.
The HKLM uninstall GUID is generated at install time and varies between versions — query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ to find the current entry by DisplayName.
Flameshot does not register file associations.
