Although Windows 11 22H2 won’t be officially available until September 20, you can download the latest Insider preview ISO file using the “Windows Insider Preview Downloads” page or with the “UUP Dump” tool to perform a clean install or an in-place upgrade on a spare computer or virtual machine.

“UUP Dump” is a tool that allows you to create a custom Windows 11 ISO file from any public preview. The tool is a collection of other tools and scripts to download the latest builds from the official Microsoft servers and create an unofficial ISO file you can use to install the operating system. On the other hand, the “Windows Insider Preview Downloads” page also offers the same download. However, previews on the page are only available when Microsoft publish them.

Since the Windows 11 2022 Update is still under development, remember that features and experience may not work as expected, and you may come across problems, even data loss. It’s recommended to create a backup of your computer before installing this version. You have been warned.

This guide will teach you the steps to use the UUP Dump tool to download the ISO file for any publicly available preview of Windows 11 (version 22H2).

Important: The recommended and supported method is to get Insider builds using Windows Update or download the official ISO files from the Microsoft site when available. Use these instructions at your own risk. However, either method you choose will download the image from the Microsoft servers.
