UnattendedWinstall is a tool for automating Windows 10 and Windows 11 installation and customization using Microsoft Answer Files.
The tool addresses the problem of repetitive manual Windows setup by leveraging Microsoft's native Answer Files feature to automate debloating and customization during installation. Answer Files are XML-based configuration files that Windows setup reads to apply settings, uninstall apps and features, and modify system configurations without user intervention. This approach runs directly on official Microsoft ISOs, avoiding the need for modified installation media, and provides full transparency since all changes are inspectable in the answer file itself.
Developers and system administrators managing multiple machines should consider this tool if they want to standardize Windows deployments while maintaining control over what gets installed and configured. It suits scenarios where reproducible, auditable setups matter more than graphical simplicity. The tool comes with pre-configured answer files optimized for personal use, but the README acknowledges that users unsatisfied with defaults can create custom answer files using alternative generators like Winhance or Schneegans' tools, both of which have accompanying video guides.
The project maintains detailed documentation for nearly all configurations and registry tweaks directly in the repository, allowing users to inspect and modify the answer file in standard text editors. Development activity shows engagement with the community through GitHub discussions and a Discord server for feedback and support. The maintainers provide tested configurations for multiple Windows versions and architectures, indicating ongoing validation work across different system variants.
