What is Cache
A cache (pronounced CASH) is a place to store something temporarily. The Xbox 360 caches files on the Xbox 360 Harddrive to optimize load times and gamedata for instant access.

Let's face it sometimes games bog down (say Bioshock or Oblivion for example) due to the cache being full, or just too many/bad updates. Well here is how to clear the cache and remove all updates.

1) Go to the "system" blade


2) Select "memory" and you should get this


3) Press Y on the Hard Drive symbol and you should get this


4) Press X,X, Left Bumper, Right Bumper, X,X and this message will pop up


5) Select Yes and it will work its magic and clear the cache and game updates
