--
-- Retrieves the encrypted administrator password for an instance running Windows.
--
--
-- The Windows password is generated at boot if the @EC2Config@ service plugin, @Ec2SetPassword@ , is enabled. This usually only happens the first time an AMI is launched, and then @Ec2SetPassword@ is automatically disabled. The password is not generated for rebundled AMIs unless @Ec2SetPassword@ is enabled before bundling.
--
-- The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.
--
-- Password generation and encryption takes a few moments. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.
