There is a LOT of odd stuff (see attached) such as if you want to image your system it can't be over 10GB , have to have enough C: space and you must install to d:\users\username\ (whereas the Amazon workspaces just says install to D:).
In my experience, I was never able to get the imaging to work properly on Amazon Workspaces. I believe I looked at it and it was a constant upsell - more space, store files in a specific location (which is poorly documented until you try to pull the trigger and actually make an image). After you've installed and configured three applications it's a little tough to move them to exactly where Amazon needs, then you learn you don't have enough disk space to image.
