Hardware Lab kit – No change. Since WHCP requirements will persist in Windows 10, version 21H1, the HLK will also remain the same. There will not be a new HLK release in Windows 10, version 21H1. As both Windows 10, version 2004 and 21H1 OS can be used for Windows 10, version 2004 qualification, they will be recognized as meeting the Windows 10, version 2004 qualification.The post lends further credence to the rumors that this year's Spring update will be a small cumulative update. Typically, the Windows 10 release cycle consisted of a major Spring update and a minor Fall update -- but this year the roles are reversed. This year's Fall update is expected to deliver a wide variety of new features, including an overhaul of the Windows 10 user interface. The latter is known as project "Sun Valley."
