Other Configuration Manager-related features and issues
Hi, @RuKo
Thank you for posting in Microsoft Q&A forum.
Based on the information available, SCCM reports Windows 11 workstations as Windows 10. However, to distinguish devices running Windows 11 in SCCM, you can use the Operating System Build device property for build number 10.0.22000 or later. The OS deployment images and upgrade packages for Windows 11 show the image name as Windows 10. This is by design.
As for future updates of SCCM, it's possible that Microsoft may release updates to improve the reporting of Windows 11 PCs in SCCM as and when there are new releases. However, there is no official word on this yet.
