The coming Windows 10 “May 2020 Update” is possibly at its final build (19041.207), and is currently available for Windows Insider Program testers using the “Release Preview ring,” according to a Thursday Microsoft announcement.   Microsoft lists the new features in the Windows 10 May 2020 Update (also referred to as “version 2004” and “20H1”) in this “What’s New” document. Typically, Microsoft releases two feature updates to Windows 10 per year, one in the spring and one in the fall, which essentially are new operating system releases.
