Microsoft has been testing the final version of the Windows 10 2020 update for quite some time, and the push for this massive update is expected to begin at the end of this month. Until then, it was only open to the internal surveyors of the slow channel and the release preview channel. Now, Microsoft has quietly released official ISO files through My Visual Studio downloads (formerly MSDN channels).
These ISos were first discovered by Twitter user WZorNET, and you need an active subscription to My Visual Studio Download to download these files.
