# WindowsImage

Select the latest version of the indicated Windows version.

This Machine Image automatically updates to the latest version on every
deployment. Be aware this will cause your instances to be replaced when a
new version of the image becomes available. Do not store stateful information
on the instance if you are using this image.

The AMI ID is selected using the values published to the SSM parameter store.
