In other words, it is a virtual version of a disc. ISO files, also called ISO images, represent a single file of an entire DVD or CD. There’s a way to create a ISO file of basically any Windows 10 Preview build you want, but it’s not an official way, approved by Microsoft.

However, if you can’t wait for Microsoft to officially release an ISO file, and have a good reason to download it, and create an installation media, it’s actually possible to do that. You can download official ISO files for the Anniversary Updates, and for different Windows builds, but you can’t download an ISO file of the latest build released. Microsoft usually releases Windows 10 ISO files for commercial versions, or when a certain build enters the Slow ring. This means you can’t find an ISO file of that build, and install it manually while it’s still available on the Fast ring only. When Microsoft releases a new Windows 10 build to Insiders on the Fast ring, it is usually only available through Windows Update.
