How to download Windows 11 ISO image using UUP dump

Let’s take a look at how to download and create Windows 11, Windows 10 and Windows 11 Insider Preview ISOs using the UUP Dump service.

Given that Microsoft rarely releases public ISOs of insider versions of Windows 11 and Windows 10, it would be important to consider an additional way to obtain Windows 11 and Windows 10 ISOs.

UUP Dump is the most practical and easiest way to get ISO images of any version of Windows 10 or Windows 11 Insider Program. Using the UUP Dump service, images can be created immediately after Microsoft announces a new build. UUP Dump creates a boot configuration file of your choice, downloads the required files directly from Microsoft servers, and finally creates an ISO image.

Please note that you do not need to join the Windows Insider Program to install and use Insider Builds. You can download and install any build of the Insider Preview program using the UUP Dump service, and when an update to an installed build is released, download the build for the new version and update it over the installed build. You can also use cumulative updates.

This article will show you how to use the UUP Dump service to get any Windows 11 and Windows 10 Insider Channel ISO images.

If you are going to create an iso image of the Windows 11 operating system using the UUP Dump service, I recommend that you familiarize yourself with the minimum system requirements for Windows 11 first.

How to create a Windows 11 Insider Preview ISO using the UUP Dump Tool:

Despite the detailed description of how to create an image, downloading an archive and then creating an iso image is as simple as possible and comes down to a few steps.

Open the UUP Dump service website:

and select the required insider channel in the Quick options column. You can also use the search box to find the OS build you want.

Select the preferred update channel and then the architecture bit. Please note that Windows 11 is currently (July 2021) only available on the Dev update channel and is not developed on x86 / 32-bit. It takes some time to create an ISO image from the downloaded UUP files.

Choose the mount you need. For example – Windows 11 Build 22000.120 (Dev).

Select your preferred language from the Language box (for Russian – Russian) and click the Next button.

In the next step, select the editions you want to download – Windows Pro or Windows Home. Note that the Windows Team edition is the Enterprise edition for use on the Surface Hub, and the N edition is regular Windows editions without multimedia components like Windows Media Player. N editions require a specific product key and are not activated with standard Windows product keys.

I recommend choosing only the Home or Pro version (or both) depending on your needs. Click the Next button to continue.

In the next window, we leave the default options such as Download and convert to ISO (Download and convert to ISO) and Include updates (convert Windows only) (enable updates if available). Click the Create download package button.

After clicking the create download package button, you will be prompted to download the ZIP archive. Download this file, it will be small. Open the file in any convenient way. We extracted the file to the root of the C drive (C:).

Open the folder where you unzipped the archive and run the uup_download_windows.cmd command line file.

If the SmartScreen filter is triggered during startup, click the More > Run anyway button in the window that appears.

The UUP Dump script starts downloading the required UUP files.

After the download of the UUP files is complete, the script will start creating the ISO image. An indication that the download is complete and the ISO image is starting to render is when the background color changes from black to blue.

When the rendering is complete and you are prompted to close the command line, press “0” to close it.

After the compilation is complete, the ISO image can be found in the folder where you unzipped the ZIP archive. The finished image of Windows 11 Build 22000.120 (Pro + Home), created using the UUP dump according to our instructions, can be downloaded here.

After creating a Windows 11 or Windows 10 ISO image, you can create a bootable USB drive with it or connect it to your computer and run the “Setup.exe” file (double click the image, then navigate to the inserted disk) and the executable Setup.exe to update the system to a newer version. run the file.
