    The .reg entry wont work for me.
    The Entries are in the Registry, but not in the Context Menu.

    @jojo2005, the question is, Context Menu of what? The entry only gets added to Directories - i.e. the root of the iso files, containing:
    sources\
    support\
    boot\
    efi\
    setup.exe

    ... etc.
    It even works in windows 11 restricted menu, so I don't know why it does not work for you. It could be some other context menu hijacking the same entry (I've reused extract verb).
    Open cmd and enter: reg query HKCR\Directory\shell\extract\command
    And see what's there. It should contain gp 'Registry::HKCR\MakeISO'

    The registry entries should work (for directories only) but there's a shortcoming: You won't get the opportunity of entering a volume label for the ISO.

    @jojo2005,
    is the target folder writable (because the iso gets saved in the same path) or are you trying it directly on a mounted iso (lol)?
    what is your windows version?
    are you using a limited or administrator account?
    have you checked your antivirus status (maybe it gets blocked somehow)?

    I did some tests, and seems language related.
    When i switch my System to English Language, the context entrys are there and when i switch to my nativ language, the entrys are gone.

    I don't think it's needed. I've made images larger than 4.5 GB and can boot them just fine in VM / USB. I'm positive dual-layer dvd would also boot fine, most iso burners already take it into account or simply burn larger files last.
    The script as-is also puts larger files towards the end of the image.
    I might try to explicitly do it when I will refactor it.

    Might want to mention the OS language that it does not show in so that I can investigate it. Otherwise I won't be able to.

    What do want exactly ?
    multiboot iso for CD/DVD (Bios and Uefi booting) --> cdimage, oscdimg
    or only bios booting ? third party tools like UltraISO (they cant both from CD/DVD)

    Because it's very easy to open an existing ISO in a ISO mastering tool, drag the install.wim into the sources folder and hit the save button.

    That makes sense. UI can make things a lot easier.

    Actually I know for a fact that UltraISO can do both

    To create a boot iso that will boot in both secure uefi and legacy, select etfsboot.com than press ctrl + alt + i and than select efisys.bin

    Then you'll be able to boot into both.

    When you open an official or not previously modded ISO it will still have the same capabilities.

    Win 8+ ISO/DVD can boot both, USB needs to be specifically created to be bootable.

    I used to use imgburn to save modified iso, while it can boot into some uefi bios not all are compatible. For example: ISO's created with imgburn are not compatible with uefi virtual machines nor are they compatible ventory USB.

    IMGBurn was fine for video ISOs, never a good tool for OS ISO mastering.
