Creating a new Windows instance from a trasferred backup

Hello,

I recently trasferred an image of a Windows VM from a different public cloud account to a project in my account. I can see the image listed in the project's console under Storage/Instance Backup.
Now I'd like to create a new instance with that backup, clicking on the Create Instance option.
It seems, however, that it's only possible to create Linux instances (no Operating system choice, and an SSH key is mandatory).
Is it possible to use the backup image to create a Windows instance ?
Thanks
