How to get Windows Insider Fast Ring ISO for latest build


The Windows Insider team has chosen not to release Insider ISO images until some time after a build gets released to the Slow Ring. There have been a few exceptions, but usually ISO images will be available only after a Slow Ring release. For us Fast Ring Insiders, this might occasionally be a problem. You might want to perform a repair install, or test how the latest build works in a clean install. UUP Dump is a tool to get a Fast Ring ISO only minutes after a new Insider build has been released.

According to its author, known as abbod1406, “UUP Dump is an automated windows command script to process Microsoft Windows 10 UUP (Unified Update Platform) files, allowing to build / convert them into a usable state (ISO / WIM)”. In this post I will show how to use UUP Dump to create an Insider Fast Ring ISO.

UUP Dump: Download and Convert

Go to https://www.uupdump.ml/. Select Fetch latest build:

Select your bit architecture (x86, x64, arm64) and click Fetch updates:

In following screen, simply click Next:

Select your language:

Select edition (only Home, Home N, Pro and Pro N available):

Click Download using aria2 and then convert:

Save the ZIP archive, unblock it by right clicking the ZIP file and selecting Properties, then Unblock:

Extract the contents of the ZIP file by right-clicking it and selecting Extract all. When done, run the aria2_download_windows.cmd batch file:

UUP Dump starts and will first download the UUP files:

When downloaded, the ISO conversion starts automatically. When done, the ISO has been created:

ISO can be found in the folder where you extracted the ZIP archive.

That’s it!

    It is, indeed, simple.

    Only thing I do differently is that I DL all editions instead of a specific one (Home / Pro / Home N / Pro N) so my single .ISO serves multiple purposes.

    I’ve also taken to saving the actual downloaded .ZIP file along with the resulting .ISO in case something screwy ever does happen with the .ISO building process (it shouldn’t, I know, that set of commands is very thorough, but still).
