Windows 10 20H2 and 21H1 show as 2009 in the Inventory page (4318153)

After upgrading a Windows 10 device to Windows 10 20H2 or Windows 10 21H1, it is noticed that in the inventory - device detail page it reflects as Operating System Release 2009.

UPDATE: This issue has been fixed with the release of SMA version 12.0 . Make sure to update the agents to version 12.0 as this fix is agent-side. For any previous versions, follow the workaround below.

Each Windows 10 Update starts with a development codename. In recent years, Microsoft has simplified these.

For example, Windows 10 20H2 became the October 2020 Update. It was named “20H2” because it was planned for release in the second half of 2020.

Windows 10 has version numbers which are different from the development codename. The Windows 10 October 2020 Update is technically Windows 10 version 2009. The first two digits represent the year and the last two digits represent the month.

This information is stored in the Registry Key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion where 20H2 represents the DisplayVersion and 2009 the Release ID.

To work-around this situation during the investigation:

1. Create a custom inventory rule to return the  OS Display Version
2. Create a custom inventory rule to identify devices with 20H2 installed
3. Create a custom inventory rule to identify devices with 21H1 installed

Any one or all three of the above can be used to then create advanced searches, smart labels, and/or reports. Often the only one needed will be the first one, but the others are provided as alternatives to quickly distinguish between the two without having to look at the value returned.

After creating the desired custom inventory rules, an inventory will need to complete for all devices. Once inventories have completed, it is possible to create reports, advanced searches, and/or smart labels to use for tasks that need to target these OS release versions. For any questions or concerns on how to utilize the rules above, please feel free to contact technical support.
