MSFS State Keeper

MSFS State Keeper is a small Windows tray application that preserves selected cockpit settings between flights in Microsoft Flight Simulator 2024.

It safely restores and records an allowlisted set of settings, including radio and navigation frequencies, transponder code, ADF, parking brake, altimeter pressure, exterior lights, heading bug, and pitot heat. Profiles are kept separately for each aircraft identity (TITLE + ATC_ID).

Download and run

1. Download MSFS-State-Keeper-portable.zip from the latest GitHub release.
2. Extract the entire ZIP to a folder of your choice.
3. Run MSFS-State-Keeper.exe.

Python and installation are not required. Keep the executable together with its _internal folder.

How to use it

1. Start Microsoft Flight Simulator 2024 and load an aircraft.
2. Wait for the State Keeper icon in the Windows notification area to turn blue.
3. Move the mouse pointer over the simulator window and press Ctrl or Shift to restore the saved profile.
4. The icon turns green after restoration. From then on, supported setting changes are recorded automatically.

Tray icon colors:

• Yellow - waiting for MSFS.
• Blue - connected; profile restoration is pending.
• Green - profile restored; supported changes are being recorded.

Right-click the tray icon to restore the profile manually, enable automatic restoration, pause recording, open the profile file, show the console, select Polish or English, or exit. The language changes immediately and is remembered between application sessions.

Local data and safety

Profiles, settings, and logs are stored in:

%LOCALAPPDATA%\MSFS State Keeper

The application runs locally. It does not install files into MSFS and does not write to the simulator's installation, package, Community, or LocalState folders.

MSFS State Keeper intentionally supports only a safe allowlist of settings. Aircraft-specific systems and arbitrary LVARs are not restored.
