This post describes the steps to use UUP Dump to download and create an ISO file of the latest builds for Windows 11.

UUP Dump helps you download the latest ISO file for any preview build of Windows 11 available in the Dev and other channels. In addition, if your Windows PC is enrolled in the Microsoft Insider Preview program, you can upgrade to the latest builds without a third-party tool.

On the other hand, UUP Dump can get the latest builds almost immediately after release. The tool will fetch and download individual packages of the builds from the Microsoft servers and create an unofficial ISO file that you can use to install on your machines.

Below is how to use the UUP Dump tool always to get the latest ISO builds of your favorite operating system.
