There's quite a lot going on behind the scenes when you launch an EC2 instance, and host load, network load and Windows itself can all increase the amount of time it takes between clicking 'Launch' and having the password generated and ready for extraction.

15 minutes is the 'usual' amount of time it can take, but I've had VMs take 20-30 minutes to go from cold to ready-to-use. It's the nature of the environment that your VMs run in - sometimes it just takes a bit longer.
