Discontinue Windows fast launch for a Windows AMI, and clean up existing pre-provisioned snapshots. After you
disable Windows fast launch, the AMI uses the standard launch process for each new instance. Amazon EC2 must
remove all pre-provisioned snapshots before you can enable Windows fast launch again.

<note>
<p>
You can only change these settings for Windows AMIs that you own or that have been shared with you.
