You can use [dockur/windows](https://github.com/dockur/windows) for that. It shares many of the same features, and even has completely automatic installation.
### How do I run a Linux desktop in a container?
You can use [qemus/qemu](https://github.com/qemus/qemu) in that case.
### Is this project legal?
Yes, this project contains only open-source code and does not distribute any copyrighted material. Neither does it try to circumvent any copyright protection measures. So under all applicable laws, this project will be considered legal.
