After choosing which one you want, the app will download the referenced ESD file, export the selected image from it, and create an ISO file that can be used to install the OS. All total, there are 5174 combinations (although some of those don’t actually exist, more on that later). After downloading both the Windows 10 and Windows 11 manifests, it will let you choose between OSes (Windows 10 22H2 and Windows 11 22H2), architectures (圆4, ARM64, x86 ), languages (lots of them), and Windows editions (lots of them too). So I created my own app to do the whole process. But as we saw a while back, the mechanism being used behind the scenes is actually reasonably straightforward: there are manifests published by Microsoft that point to images (ESD files - more on those here), and those images can be turned into ISOs with a few ADK-driven tweaks. But there are some limitations, like being architecture-dependent and only presenting a limited list of Windows editions. Now there is a Windows 10 version and a Windows 11 version. Since the initial Windows 10 release, Microsoft has made available the Media Creation Tool (MCT). Note: See the bottom of the log for the change history and latest version.
