Getting "Your device is no longer receiving security updates" on machines running Windows 10 IoT Enterprise LTSC 21H2 19044.6456

My understanding is this should be supported till 2032?

    Hi,

    To resolve this, please:

    1. Ensure the latest Servicing Stack Update (SSU) and Cumulative Update are installed (you can manually download them from the Microsoft Update Catalog).
    2. Run winver and confirm the edition reads exactly “Windows 10 IoT Enterprise LTSC 2021”.
    3. If the message persists, clear the Windows Update cache (net stop wuauserv, delete SoftwareDistribution, then restart the service) and recheck.

    If this explanation clears things up, please hit “Accept Answer” so others can benefit from it too! 😊

    Kind regards,
