// When you enable Windows fast launch for a Windows AMI, images are
// pre-provisioned, using snapshots to launch instances up to 65% faster. To create
// the optimized Windows image, Amazon EC2 launches an instance and runs through
// Sysprep steps, rebooting as required. Then it creates a set of reserved
// snapshots that are used for subsequent launches. The reserved snapshots are
// automatically replenished as they are used, depending on your settings for
// launch frequency. You can only change these settings for Windows AMIs that you
// own or that have been shared with you.
