/#Action=EnableFastLaunch

http://ec2.{region}.amazonaws.com/#Action=EnableFastLaunch

<p>When you enable faster launching 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.</p> <note> <p>To change these settings, you must own the AMI.</p> </note>
