    =========================
    2xH2_Creator_17.5
    =========================
    Update to 26x00.9278


    - Added KB5121794-PSFX (Enablement for 26H2)

    - Added the file _HowToUse_2xH2_Creator.chm

    - The GenerateUpdateList.ps1 script (all versions) has been tested multiple times with mixed results:
    a) Sometimes it creates the all.txt file correctly.
    b) At other times, it fails to resolve the URL, resulting in an incomplete all.txt file (missing the LCU2).
    Consequently, it is not yet 100% reliable.
    In light of this, we will not be adopting this script—at least for the time being.
    We will continue to update the all.txt file manually.

    - Some adjustments applied

    Test with:
    - pt-br_windows_11_enterprise_ltsc_2024_x64_dvd_2bb6b75b_2.iso
    - 26100.1742.240909-0928.GE_RELEASE_SVC_REFRESH_CLIENTBUSINESS_VOL_X64FRE_PT-BR.ISO

    Hi SunLion, a few small things

    When [20] is set to no desktop icons
    W112xH2+.cmd adds This PC icon back

    When Modern calculator is selected it shows both modern and legacy in start menu can it only show modern instead?
    When EnableMediaPlayer is enabled shouldn't it just use the legacy version? why does the actual app get installed?

    Is there any point of installing .NET Framework 3.5 if you use this reg?

    [HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework]
    "OnlyUseLatestCLR"=dword:00000001

    [HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\.NETFramework]
    "OnlyUseLatestCLR"=dword:00000001

    Thanks for your work and everyone contributing.

    (OP)
    The script doesn't add any shortcuts to the start menu when enabling Classic Calculator.

    But I haven't tested all the possible options either...

    Which edition of Windows did you use?

    To facilitate my research on this.

    As for the other issues:
    You're right. I'll remove that from the W112xH2+.cmd file.
    But I'll keep the display of the ThisPC+Bin icons as the default.

    The script removes all ProvisionedAppxPackages, including MediaPlayer.
    Then, the script integrates the latest Appx packages, including MediaPlayer (if enabled).

    Yes, it makes sense for those using older apps that require .NET 3.5.
    The registry keys won't interfere with those options.[/quote][/quote]

    [3]Build to create: Enable26H2
    [13]Calculator: Modern


    I only ask because I too needed 3.5 for a older app that would always nag about not having it installed, but ever since those reg keys it never asked for it to be installed again. So I haven't installed 3.5 since. But I wonder if those reg keys won't satisfy every app and you actually need 3.5 installed? This is just a general question if anyone knows.

    That’s really a bit of a mystery. Some apps always complain.

    For my part, I always enable net35, just to be safe.
