Your platform offers powerful user-managed provisioning unlike any other. It would be a great benefit to the world if you offered native windows server droplets. There are no other providers that have an account dashboard where users can create, scale, extend, image, restore, and load balance servers SO easily!!
Windows server can be hosted on a droplet but it is a cumbersome process and other essential features of your system, like backups, images, snapshots, don't work with the work-around.
