# Cancel a stack update
<a name="using-cfn-stack-update-cancel"></a>

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.

1. On the navigation bar at the top of the screen, choose the AWS Region where the stack is located.

1. On the **Stacks** page, choose the stack that's currently being updated. Its status must be `UPDATE_IN_PROGRESS`.

1. Choose **Stack actions** and then **Cancel update stack**.

1. To continue canceling the update, choose **Cancel update**. Otherwise, choose **Cancel** to resume the update.

The stack proceeds to the `UPDATE_ROLLBACK_IN_PROGRESS` state. After the update cancellation is complete, the stack is set to `UPDATE_ROLLBACK_COMPLETE`.
