Updating multiple endpoints to 20H2 via Software Library > Windows 10 Servicing > All Windows 10 Updates > Feature Upgrade 20H2. I've come across two computers so far that show in Software Center as having successfully completed the upgrade, and System Properties reports 20H2. They have the desktop environment of 20H2 as well.
BUT, as mentioned, "gcim Win32_OperatingSystem" from Powershell shows 1903 still, and MECM shows them as 1903 also. :/
Anyone come across this yet? I can't push the update again because the client thinks it was already successful.
