Guide to Downloading Windows 11 23H2 ISO File Post 24H2 Release

• After the launch of Windows 11 24H2, you can obtain the Windows 11 23H2 ISO file by employing the UUP Dump script, allowing you to download the installation files and assemble a customized ISO. This custom ISO can then be utilized with the Rufus application to construct a bootable USB installer.

Even though Windows 11 24H2 has been released, obtaining the ISO file for Windows 11 23H2 for a clean installation of the earlier operating system remains possible through alternative methods.

Typically, following the introduction of a new Windows update, Microsoft enhances the “Installation Assistant” and “Media Creation Tool” for seamless upgrades to the latest version (in this instance, 24H2), which complicates the process of downgrading using these official utilities.

If you find yourself needing to revert to a previous version, Windows recovery settings could allow you to uninstall version 24H2. However, if that option is unavailable or ineffective, you can still acquire the Windows 11 23H2 ISO file post-release of version 24H2 by utilizing the UUP Dump tool along with Rufus for creating your bootable installation media.

This guide details the steps necessary for downloading the ISO file of a prior Windows 11 version.

3. Choose the latest Windows 11 23H2 build to download the ISO file (x64) using the option, for example, Windows 11, version 23H2 (22631.xxxx) amd64.

Upon completing these steps, the script will automatically download necessary files from Microsoft’s servers and generate the Windows 11 23H2 ISO file, which you can then use to create bootable media.

How to Create a Bootable USB Drive

To set up a USB drive for Windows 11 23H2, follow these guidelines:

1. Visit the Rufus website.

2. Click the link in the “Download” section to get the latest version.

3. Double-click the downloaded executable file to open Rufus.

10. Press the Start button to initiate the process.

11. Click the OK button if you wish to bypass any custom settings.

12. Confirm the deletion of all data on the USB drive by clicking the OK button.

Once you’ve finished these steps, the bootable USB drive is ready, enabling you to install the older version of Windows 11 via a clean setup or an in-place upgrade.

If you prefer to streamline the process of accessing an earlier Windows version, it’s prudent to download the ISO file as soon as it’s released, storing an offline backup whenever a new update emerges.

While it remains feasible to download an earlier version of this operating system, the future availability of the script is uncertain. Thus, it is advisable to download the image files promptly.
