📝 Notes

  • Standalone Syncthing (no installer) writes no registry keys — it is a portable binary; config lives in %LOCALAPPDATA%\Syncthing\.
  • SyncTrayzor is the popular Windows GUI wrapper that adds a tray icon, auto-start, and browser-based config.
  • Syncthing's web UI runs at http://127.0.0.1:8384 by default — no registry key stores the port (it's in config.xml).
  • For headless/service installs, use NSSM or the official Windows service wrapper.
