It seems like Microsoft has determined that Windows 10 Build 19041.264 is much more stable that Windows 10 Build 19041.208, and decided to release new ISO images based on Windows 10 Build 19041.264, making the build 19041.264 the new final RTM build of Windows 10 Version 2004, aka Windows 10 May 2020 Update, codenamed 20H1.

To be sure, Microsoft no longer use the term RTM to describe the any milestone during software development cycle for a release anymore as the development is always continuing. Nonetheless, there are some significant points that a build is considered ‘final’ where the quality of build is stable and optimal, such as prior to general availability for public, released to OEM for manufacturing, or made into ISO images.

If you’re subscribers on Visual Studio or MSDN platforms, new ISO images for Windows 10 Version 2004 labeled as Updated May 2020 have been made available for free downloads. Windows 10 Version 2004 Updated May 2020 ISO images are essentially similar to Windows 10 Version 2004 final ISO images previously released, which contains Windows 10 Version 2004 Build 19041.208 with additional integrated updates and security packages that were released up to May 12th, 2020, such as Security Update for Adobe Flash Player (4537759), Servicing Stack Update (KB4557968), Cumulative Update for .NET Framework 3.5 and 4.8, and most importantly, Cumulative Rollup Update KB4556803 which brings the Windows 10 to OS version 19041.264.
