Using Amazon EC2 instances running Windows is similar to using instances running Linux and UNIX. The following are the major differences between instances that use Linux/UNIX and Windows:
Remote Desktop—To access Windows instances, you use Remote Desktop instead of SSH.
Administrative Password—To access Windows instances the first time, you must obtain the administrative password using the ec2-get-password command.
Simplified Bundling—To bundle a Windows instance, you use a single command that shuts down the instance, saves it as an AMI, and restarts it.
