This creates an iso file with the latest Windows available from the Unified Update Platform (UUP).
This shrink wraps the UUP dump project into a single command.
Just fork this repository and use Github Actions to build your own version.
Once the GitHub actions are complete, you'll receive a finished ISO image in two flavors.
- Release with the .iso file split into several parts (as GitHub doesn't allow files larger than 2GB to be included in a release). Additionally, for each release, packages are created for various systems and architectures, containing a ready-made script that downloads all parts of the split ISO and returns the finished ISO file.
- Artifacts - a single zip file, but logging in to the website is required to download.
