Since the WindUpdate is still under development, remember that features and experience may not work as expected, and you may come across problems, even data loss. However, previews on the page are only available when Microsoft publish them.
On the other hand, the “Windows Insider Preview Downloads” page also offers the same download. 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. “UUP Dump” is a tool that allows you to create a custom Windows 11 ISO file from any public preview. 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.
