You just need to trick the site to think you’re using an unsupported OS. If you don’t want to go through the extra steps, there is a workaround to download the ISO file of Windows 10 with the latest update directly without having to use the Media Creation Tool. Microsoft releases the ISO files for every new release of Windows 10, including for the Fall Creators Update, the only caveat is that when you use a Windows 10 device to download the ISO from the Microsoft support website, you’re only given the choice to get the Update Assistant or Media Creation Tool. However, if you want to upgrade early and you’re up to the challenge, it’s also possible to upgrade using an ISO file. The Windows 10 Fall Creators Update has officially arrived, and Microsoft is now slowly rolling it out to millions of devices around world.
