Good day! There is a need to create a windows server from a snapshot on DO. I understand that this is impossible, since this service requires the installation of Linux on the server. But maybe there are ways to create multiple operating systems on the server, or something like that? Can anyone come across and can help? Thank you!

To my knowledge there isn't a way to use DigitalOcean's snapshot feature with Microsoft Windows due to the changes they make on the backend which the snapshot is created. That may be changing in the future as they are rolling our custom image support so you can bring your own Linux OS, but I haven't yet seen any announcements there.
