It’s technically “late May.” So it’s not too surprising that Microsoft’s promised late May rollout of the Windows 10 May 2019 Update (also known as 1903) is kicking off today, May 21.
As of today, mainstream consumer and business users who want to manually download and install the May feature update may do so. The May 2019 Update/1903 is available on WSUS, Windows Update for Business as of today. Users who aren’t already on Windows 10 1809 (either because they weren’t “offered” it or didn’t proactively grab it) will be able to just skip over 1809 and go straight to 1903, since Windows 10 feature updates are cumulative.
