If everything that has been planned by the Redmond Giant, then the Windows 10 Fall Creators update will be the RTM which would be released in the month of September with a global rolled to happen in October as was the case with Creators Update, RTM having rolled out in March and Global Rolled out planned for April.
However users can download the RTM build in the month of September by using the Windows Insider Program/Official ISO’s or Microsoft’s Upgrade Advisor. However we could expect the download Methods to change with the Windows 10 Fall Creators Update.
