- To download the Windows 11 24H2 ISO file, open the “Windows Insider Preview Downloads” page, sign in, choose the latest preview in the Dev Channel, click “Confirm,” choose the language, click “Confirm,” and click “64-bit Download.”
- Alternatively, open the “UUP Dump” website, choose the latest Windows 11 preview, select the language, click “Next,” choose the editions to include in the ISO file for version 24H2, click “Next,” click “Download and covert to ISO,” extract the files, and run the “uup_download_windows.cmd” file.
Windows 11 24H2 won’t launch for existing devices until at one point in September 2024, but you can download the latest preview ISO file for this version now using the “Windows Insider Preview Downloads” page. Alternatively, you can use the “UUP Dump” tool to perform a clean install or an in-place upgrade on a spare computer or virtual machine.
The Windows 11 2024 Update is still under development, so not all the changes will be included. Also, the features and experiences may not work as expected, and you may encounter problems, even data loss (in some rare cases). I always recommend creating a computer backup before proceeding with the installation.
The difference between the “Windows Insider Preview Downloads” page and the “UUP Dump” tool is that the “Insider” page allows you to download the official files when Microsoft believes a build is stable enough to be available through an ISO format. The “UUP Dump” is a collection of tools and scripts to download the latest builds from the official Microsoft servers and create an unofficial ISO file to install the operating system.
In this guide, I will teach you how to download the ISO file for any publicly available preview of Windows 11 (version 24H2) and create a USB bootable media with the Rufus tool.
Important: The recommended and supported method is downloading the ISO file from Microsoft, but either method will download the image from the Microsoft servers. Use these instructions at your own risk. You have been warned.
Download the Windows 11 24H2 ISO file using Insider program
To download the Windows 11 2024 Update ISO from the Insider page, use these steps:
- Open Windows Insider Preview Downloads page.

Quick note: Currently, the next version of the operating system is available through the Dev Channel, but as we approach the release date, it will move down the available channels. Usually, when the new version arrives in the Release Preview Channel, it’s considered more stable and ready.

After you complete the steps, the final ISO for Windows 11 24H2 will download to your computer. You can continue with the instructions below to use the Rufus tool to create bootable USB media.
