It is known that Dev versions of Windows 11 are not released in ISO format. Below we will see how you can use UUP Dump to download the Windows 11 Insider file to ISO for versions of Dev channels that do not have an official installation image.
UUP Dump is a free service that provides a set of scripts and tools for downloading UUP files directly from Microsoft servers and creating ISO files from them.
The service is customizable, meaning you can choose which version you want to download, which language it should include, and which features. The best thing about UUP Dump is that it does not require you to be registered with Windows Insider to download and create ISO images.
However, when the Windows 11 ISO images are officially released, we recommend that you use the official files. You will be able to download them as you download versions of Windows 10.
So the UUP Dump will help you if you need to reinstall an Insider Preview version from scratch or on a VM.
