[German]Microsoft is again expanding the range of machines to which the Windows 10 May 2021 Update (21H1) will be offered after its release in mid-May 2021 (see Windows 10 May 2021 Update (21H1) released (May 18, 2021)). This is now the second expansion, having already been distributed more broadly in early June 2021 (see Windows 10 May 2021 Update (21H1) is distributed more widely via machine learning).

Windows 10 May 2021 Update (21H1)
The Windows 10 May 2021 Update internally carries the version designation 21H1, and is the first feature update for 2021. The feature update is intentionally designed to deliver key features that improve security, remote access, and quality. Distributed, this update will only be available for select devices running Windows 10, version 2004 or later.
Windows 10 21H1, similar to Windows 10 version 1903/1909 and Windows 10 version 2004/20H2, will be rolled out only as a minor feature update for the old 2004 and 20H2 versions. For this purpose, the changes are already prepared in the existing Windows 10 versions 2004 and 20H2 via monthly updates. For the release, only the few KByte Enablement Update KB5000736 is required via Windows Update or WSUS. However, this is only offered on suitable machines and will not be available via the Microsoft Update Catalog.
How to get Windows 10 V21H1
Interested users can so far open the Windows Update settings page on Windows 10 2004 and 20H2 (Settings > Update & Security > Windows Update) and select the Check for updates button there. Until now, however, the update was only offered to a very limited circle of machines that were known to have no compatibility issues.
Then, in early June 2021, the circle of machines was expanded as Microsoft began training its machine learning distribution algorithms (see Windows 10 May 2021 Update (21H1) is distributed more widely via machine learning). In the Windows 10 version 21H1 status area, Microsoft announced the next stage of the rollout on June 22, 2021. While there it still states:
Windows 10, version 21H1 is available for users with devices running Windows 10, version 20H2 and Windows 10, version 2004, who manually seek to "Check for updates" via Windows Update.
But it is now said (see screenshot below) that Microsoft has started the next phase of the rollout. Using the machine learning training it has done so far, Microsoft is now increasing the number of devices selected for an automatic update to Windows 10, version 21H1. This mainly affects devices that are nearing the end of the maintenance period.

The Machine Learning (ML) model will be further trained to detect problems and stop the rollout if necessary. The goal is to automatically upgrade compatible machines to Windows 10 version 21H1 later. Microsoft continues to train machine learning algorithms throughout all phases of the staged rollout. This rollout in waves, after all, has been in use for many years, and machine learning is also used to detect deployment issues early and suspend delivery on incompatible machines.
