Windows 11: Download build 26100 ISO file with UUP Dump

The tool includes scripts to download any Windows 11 Insider Preview build from the Microsoft servers and then convert the image into an ISO file that you can use for a clean install or an in-place upgrade.

Update: These instructions still apply in 2024.

Important: Extract the archive directly to the root of your drive. Otherwise, you might receive an error (the script doesn't like long directory names)

Lifesaver - I wanted to use a version higher than 21364 for the WSL2 graphical app update, but with Windows 11 insider builds it's become impossible to access - UUPDump has the latest Windows 10 insider build. Thanks a bunch!!

For anyone using this and staying organized by making folders that are named UUP Dump. You will get an error. The fix is to not include spaces so make it UUP_Dump.

Current directory contains spaces in its path.
Please move or rename the directory to one not containing spaces.


When I run the Command Prompt to download the ISO file. I don't think I have any space in the path, any solution to this please?

Everytime I try this, I reach a blue screen and get spammed with tons of texts that all end in "Access denied" and the .ISO file is never made. I ran as admin, I completely disabled windows defender.

IMPORTANT: for some reason when the terminal thing is opening it, when you have something selected it will pause the process, if you accidentally select something just hit escape.

ALSO: To get rounded corners in Virtual Box, I found you have to make sure these settings are set:
- 3d acceleration on
- set to "windows 10"
- Graphics controller set to VBoxSVGA

[branxyt]

[than]

it worked but when it install it install forever how to fix this it not giving the iso file

[sylvoen]

that website is very cool because it says it'll give you an iso for 22000.100 but actually ends up giving you an iso that installs 22000.1

[mohandmohand]

Use internet when you do this steps or no???

[adrianorodriguez]

Hello! After trying several times, when converting to ISO it says "access denied"... TWICE. No matter if you try to rename the folder into a short name, it just doesn't work. Could you please help me? Thanks!
