    @SunLion

    Just to let you know that even though I'm trying out 11 IoT LTSC I'm not participating much in this thread as much as I'd like since I've realized that if I want to make the in-place upgrade from 10 to 11 work well I need to run it with an untouched 11 LTSC ISO since my current 10 is already slimdowned.

    Take care!

    @SunLion I'm testing 26H1_Creator_1.7 like your other SD releases is it possible to update/add uwp apps by placing them into the 26H1_Creator_1.7\UUP\APPX directory?
    Unlike your other builds their does not appear to have any uwp apps in this directory?

    sainfo, hello!

    Is file 1.xml required for conversion to IOT LTSC? If so, can it be published?

    in script
    "%DISM%" /english /scratchdir:"%~dp0Data\Temp" /image:"%~dp0Data\Temp\Mount" /apply-unattend:Data\Files\sxs\1.xml

    Thank you

    Hi @Mavericks Choice

    Since this is the latest version, I opted not to use UWP apps, at least not yet.

    But it is possible to add them. To do this, we need to add the integration code to the script.

    Do you have any UWP apps you'd like to include in the APPX folder?

    I was just checking and I understand that there shouldn't be any new APPX packages for this version, at least for a while.

    The ProvisionedAppxPackages are a new generation.

    So I made some adjustments to the code to remove the ProvisionedAppxPackages, especially to avoid removing those related to some internal systems, such as Store, Defender, Media Player, and others.

    If the option is not to disable those mentioned, the related ProvisionedAppxPackages should not be removed.

    I believe this will work well.

    I just wanted to add the simple windows photo viewer 9NV2L4XVMCXM its useful for my needs, it does integrate fine post install with winget,
    though would be handy to integrate this to the wim.

    Is this it?
    Microsoft.Windows.Photos_2025.1104.923.0_neutral_~_8wekyb3d8bbwe

    If that's the case, replace the code below with what starts on line 1173 in the script:

    Has anyone experienced using SD 11 with a setupcomplete.cmd that the runonceex.cmd runs simultaneous in that it interrupts the setupcomplete.cmd & reboots the pc?
    I have a single admin user account & use setupcomplete.cmd to run my 3rd party apps etc.

    To do this, you could install what's in RunonceEx using setupcomplete.cmd.

    That way you wouldn't use runonceEx, only setupcomplete.cmd.

    In our script, I use a few apps installed with runonceEx and only install a few with setupcomplete.cmd, which is reserved more for script execution.

    When there are many apps in both runonceEx and setupcomplete.cmd, conflicts almost always occur...

    Try it and see if it works.

    Yes I used setupcomplete to call runonceex & it appeared to wait & install as expected, few small issues/items to tidy up & I will be ready to switch permanently to Win 11!
