For emulating Windows, there is [dockur/windows](https://github.com/dockur/windows), which is more dedicated to that purpose. It has all the same features as this container, but additionally includes all the necessary drivers, and it will even automatically download the correct ISO image from the Microsoft servers.
To enable Windows booting, add the following line to your compose file:
```yaml
environment:
BOOT_MODE: "windows"
```
But it is better to use [dockur/windows](https://github.com/dockur/windows), as it includes all the drivers required during installation.
