# Cancel a stack update


After a stack update has begun, you can cancel the stack update if the stack is still in the `UPDATE_IN_PROGRESS` state. After an update has finished, you can't cancel it. You can, however, update a stack again with any previous settings.

If you cancel a stack update, the stack is rolled back to the stack configuration that existed before initiating the stack update.
