UPDATED 9/3/2021: Windows 10 build 19044.1202 ISO file is now available for download for those who want to test version 21H2 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 the next features and improvements coming later in 2021. This media 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 do not need to download the ISO file for build 19044.1202 since you can use the “Windows Update” settings to upgrade to the latest flight through the Release Preview Channel.

After you finish downloading the official ISO file, you can use different tools like Rufus to create a USB flash drive to install the operating system. Alternatively, you can mount the ISO to begin the setup if you plan to do an in-place upgrade.
