When a new version of Windows 10 releases, an updated version of the Media Creation Tool and Update Assistant becomes available to upgrade devices to the most current version of the operating system, making it impossible to use the tool to downgrade if that is something you need to do. If you need to rollback, you can usually use the recovery option to uninstall an upgrade, but the option is only available for the first ten days, and sometimes it does not even work. However, if you must install an older version of Windows 10, you can use “Rufus” to download the Windows 10 20H2 ISO file after the release of version 21H1 on May 18, 2021. Rufus is a well-known free third-party tool that you can use to create a USB flash drive to install the operating system. But unlike the Media Creation Tool, this tool includes an option to download the ISO file and prepare a bootable media using an older version of Windows 10. In this guide, you will learn the steps to use Rufus to download the ISO file and create a USB to install Windows 10 20H2 after version 21H1 (May 2021 Update) releases.
