UPDATED 10/7: Windows 10 build 20231 ISO is now available for download for those who want to test the new version of the operating system using a clean installation or in-place upgrade.
Microsoft is releasing another official ISO file of Windows 10 in the Dev Channel to allow developers and enthusiasts to get early access to features and improvements coming in future releases. This rollout is not meant to install a pre-release of Windows 10 on your primary computer.
If you’re already a member of the Windows Insider Preview program, you don’t need to download the ISO file for build 20231, since you can use “Windows Update” from the Settings app to upgrade to the latest flight.
How to download build 20231 ISO file for Windows 10
To download the latest preview build of Windows 10 with changes coming in future releases, you need to login to this Microsoft support website. Once you’re in the download page, you will need to choose the edition, and click the Confirm button to download the file.
After you finish downloading the official ISO file, you can use different tools, such as Rufus to create a USB bootable drive to install the operating system. Alternatively, you can simply mount the ISO to begin the setup, if you’re planning to do an in-place upgrade.
