This Xbox Tip of the Week time, and this one is one you hear all the time, but may not know what it does. Clearing the cache is a simple “step one” for troubleshooting many different issues with games or apps on your Xbox 360.
Clearing the cache does not wipe your console back to the factory default settings, it does not remove your gamertag, delete downloaded themes, demos, games, etc… and does not remove your saved games. What it does is simply delete title updates for various games or apps. Then, when you re-launch a game, it will re-downloaded the latest available update from Xbox Live. Sort of like uninstalling and reinstalling software on your PC – it may not always resolve your issue, but it’s quick, simple, and worth a shot!
To clear your cache, turn on your Xbox 360 to the dashboard. Then, navigate to the right (in the current Xbox dashboard (the first one with the Metro style interface, it’s under the header Settings). Then select the System tile. Select Storage, then press the “Y” button for Device Options (when you have the primary hard drive selected). Then select Clear System Cache and says Yes.
Xbox.com Support has the full details, but the process is fairly straight forward – you probably won’t even have to visit their site for this one!
