    Hello,

    By comparing the June and July updates, several new components have been identified that appeared in July, including PowerShell-related packages and server management features.

    Taking a cautious stance, the new components that affect client systems have been dealt with. This continues to be a reserved placeholder for future notes, changes or updates.

    The thread reflects the current understanding as of July, and emphasizes that any attempts to implement these changes in future months, before official confirmation are, as always, at your own risk.

    I am open to feedback and constructive criticism. I kindly ask that you read everything carefully, as detailed as you can, that you test this procedures safely, and never use them in critical production scenarios.

    My two cents. Thank you.

    Hi,
    InstallModViaDISM contains some safeguards to ensure the previous steps have been successfully completed.

    You should refer to the guide with screenshots for 2025-11: https://forums.mydigitallife.net/posts/1897571

    The KB IDs are different versus this particular written guide, but the logical steps are still similar.

    I never tested Embedded editions. Only Windows 8.1 Pro and Enterprise, installed from the original Microsoft ISOs, then updated with an update pack online (takes about a day's work), and finally installing the patched latest cumulative update.

    My two cents. Thank you.

    Hi,
