I wrote a small GUI-based tool that uses the Windows Imaging Format (WIM) to create full backups of computer systems (operating system images) and then restore them.
The application is hosted on GitHub, is open source, and is offered under the Apache 2.0 license.
In addition, the repository includes an illustrated step-by-step guide to help get it up and running.
Maybe someone can use the solution for their purposes as well - I would be happy. Have fun with it.
The GitHub repository is named: WIM-Backup
