Windows 10 21H1, “May 2021 Update” will be the eleventh major update released on May 18, 2021.

Unlike previous releases, this will be a minor update that will only include a small set of features, changes, and improvements to complement the work done on versions 2004 and 20H2.

Also, since this will be a small release, the update will install quickly as an enablement package like a cumulative update without the need for reinstallation.

Starting February 17, 2021, version 21H1 is already available for testing through the Beta Channel of the Windows Insider Program.
