Steam Achievement Manager v1.0 — Achievement Utility
Steam Achievement Manager v1.0 by mul0 is a Win64 desktop utility for browsing your owned Steam games, viewing their achievement catalogs, and managing selected achievement states from one responsive interface.
The program loads your Steam library into a searchable game list with cover images. Double-click a game to view its achievement names, descriptions, icons, and current unlocked or locked states.
You can change individual achievement checkboxes, select every achievement for unlocking, clear every selection for locking, and submit only the states that differ from the values loaded from Steam.
An optional background-hosting feature can keep selected Steam App IDs active without launching the real games.

Browse Your Steam Library
- Start Steam and sign in to the account you want to use.
- Open Steam Achievement Manager v1.0.
- Click the refresh button to load or update your owned game library.
- Use the search field to filter games by name.
- Select a game to make the background-host control available.
- Double-click a game to load its achievements.
Game covers are cached locally so they can be reused during later sessions. While library information and images are loading, the interface keeps the related controls safely disabled until the current operation finishes.
View and Select Achievement States
- Each achievement row displays its icon, name, description, and current Steam state.
- Check or uncheck an individual row to prepare a specific achievement change.
- Use the Unlock control to check every achievement row.
- Use the Lock control to clear every achievement row.
- Review all intended changes before submitting them.
Important: The Unlock and Lock controls change the visible checkbox selections only. They do not immediately update your Steam account.
Submit Achievement Changes
- The Submit control becomes available only when at least one checkbox differs from the state loaded from Steam.
- Clicking Submit sends only the changed achievement states.
- Checked changed rows are submitted for unlocking.
- Unchecked changed rows are submitted for locking.
- After the operation completes, the visible achievement list is refreshed with the resulting states.
Achievement submissions affect the Steam account that is currently signed in. Always confirm the selected game and every changed checkbox before clicking Submit.
Background Game Hosting
- Select a game and use GAME START to start its background Steam host.
- The selected Steam App ID remains active without launching the real game.
- Use GAME STOP to stop that game's host.
- Multiple standalone game hosts can run at the same time.
- If achievements are opened for a game that is already hosted, the manager reuses the existing host instead of starting a duplicate process.
- All active host processes are closed automatically when Steam Achievement Manager exits.
