SCCM 2006 with all hotfixes
Windows 10 x64 1909

We created simple IPU with 20H2 OS package. The TS completes successfully but when I look at the system info of actual computer itself, it is still 1909. TS Status Message viewer shows no errors.

    Probably exiting right after running compatscan. Check the compat xmls under panther directory.

    @Pavel yannara Mirochnitchenko

    Thanks for posting in Microsoft Q&A forum.

    At first, maybe it's just a display problem, you can check the OS version by using methods other than using systeminfo command.
    It is suggested to check the OS version by running the PowerShell commands : (Get-WMIObject win32_operatingsystem).Buildnumber
    For more methods, please refer to this article: https://www.winhelponline.com/blog/find-windows-10-build-version-edition-bit/
    Note: This is not from MS, just for your reference.

    Secondly, could you please share your smsts.log (with sensitive information masked), so that we can confirm that whether the steps of upgrade in task sequence have been run.

    What's more, you can copy the iso file to another computer, open the iso file and double-click setup.exe to manually install the OS, in order to confirm there is no problem with the package.
    For more details, please refer to this link: https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/how-to-upgrade-to-windows-10-version-20h2-using/617a37da-8fc0-4f33-a3eb-59fe9082f925

    Thanks for your time.
