Microsoft just released the Windows 10 version 21H1, a minor feature update, that will be followed by a major update Windows 10 21H2. Now the official documentation also mentions Windows 10 version 22H2. It also seems that the 22H1 update may be entirely dropped as there is no entry for it. Probably, Microsoft will release only one Windows 10 update going forward, starting 2022.

The updated official documentation has Windows 10 version 22H2 as one of the Windows 10 versions. All Windows 10 versions are present in the list of objects in appraiser event used for Windows 10 diagnostics data.

Appraiser events


This event lists the types of objects and how many of each exist on the client device. This allows for a quick way to ensure that the records present on the server match what is present on the client. The data collected with this event is used to help keep Windows up to date.

It is clear that Windows 10 version 22H2 is codenamed “Copper” as is clear from CU22H2 entry. Windows 10 version 21H2 has three entries in the event. While one entry has “Cobalt” codenamed assigned other two entries are without CO prefix.

This update 21H2 may be one of the biggest Windows updates ever, Microsoft has hinted. So, probably two versions of Windows 10 21H2 are in works, one in the Build 2XXXX range and another in the Build 1904X range.
