    Hello Andreas, I just successfully performed in place upgrade from LTSC 2019 to 2021, all personal data have been kept.

    Before the live upgrade, I've restored my PC into virtual machine and made a test there :)

    To upgrade form one version of LTSC to another is very simple.

    I log into the computer as an admin.

    I uninstall the anti-virus as this can stop the upgrade from working.

    I copy the Windows LTSC files to a folder on the desktop.

    I run the setup.exe, and choose to keep all files and folders.

    The upgrade runs, and it takes about an hour.

    After its finished, I reinstall the anti-virus.

    OK, @Tomas Antal more how did you run this update? Was it via Windows Update normal or how? I have LTSC 2019 and would like to update to 2021, but via Windows Update until the month of 12/2021 only Windows 10 1809 update came!

    LTSC will never get automatic feature updates: that would defeat the purpose of using the LTSC in the first place.
    LTSC: What is it, and when should it be used?
