    Looks like we are out of luck. All the other files can be found in UUP - either in ISOFOLDER\sources, or in winre.wim\system32. Testplugin.dll seems completely absent from UUP files.It is part of the imagebasedsetup-media package in the real boot.wim.Seems only available from the full ESD dowload.

    Simplest alternative is to drop a menu into fake boot.wim\system32, plus a partitioner (bootice or PW etc) and something to apply the image ( dismgui or dism++ etc.)

    Siw, I have an idea and want to test it. A bit preoccupied now but later today I'll make an ISO from UUP files based on the theory, an idea I have. I upload it later tonight to OneDrive. If you could then download it, check what's if anything is missing.

    I tried to use the iso created from install.esd in a hyper-v session as a gen 2 machine, and it would not boot.

    I used same iso in a usb drive and it booted fine.

    In the end, I had to install 14986 iso (gen 2 in hyper-v) and upgrade that using 15002 iso.

    I have a keen interest in this,, my app here: Releases . Superfly-Inc/Windows-ISO-Creator . GitHub hasn't really got off the ground .. so thinking of adding a UUP plugin to it... (btw it uses native API's rather than the pre-compiled (?old) stuff the scripts use ) but it is in dire need of updating.. so will be following developments here to see if I can implement something.

    @SIW2, if you want to take a UUP ISO apart and check the boot.wim and stuff, here's one I just made and uploaded:

    ISO was made like this:
    • Using UUP files (Windows\SoftwareDistribution\Download) I created install.wim
    • Mounted a stock retail Windows 10 PRO version 1607 (build 14393) ISO originating from MSDN, copied its full content to a folder on HDD naming it ISO_Files
    • Replaced install.wim in ISO_Files\Sources with my UUP install.wim
    • Wrote iso with OSCDIMG.EXE, boot files were taken from ISO_Files\Boot and ISO_Files\Efi\Microsoft\Boot

    OSCDIMG command used:
    oscdimg.exe -m -o -u2 -udfver102 -bootdata:2#p0,e,bd:\iso_files\boot\,e,bd:\iso_files\efi\microsoft\boot\efisys.bin d:\iso_files d:\en-gb_windows_10_PRO_15002_x64.iso
    ISO works perfectly, in Hyper-V and when written to USB on physical machine. In Hyper-V tested both Generation 1(MBR) and Generation 2 (GPT).

    That indicates the 1607 boot.wim works with more recent install.wim. That is a possible workaround.

    In future, people may not have that - tf you are correct about the switch to UUP. Though I suppose some kind of iso will be available from MS.

    If the purpose is to create fully functional media from only the UUP files ( not dependant on also having regular MS install media ), then what I suggested earlier is one way.

    I suspect the simplest solution is to add (to fake boot.wim ) a menu to access some way of partitioning drives and applying the wim

    Microsoft have to release an ISO when Creators Update (version 1703 or 1704, depending on if they postpone it to April) will be released. People buying retail download version need an ISO.

    Anyway, I was surprised how perfectly this works. I need to test a bit more then update the UUP to ISO tutorial; this is far better and more reliable method than directly writing an ISO from UUP files.

    Only tested clean installs. Give me some time, I'll import a saved but not in active use W8.1 PRO vm and upgrade it. Doing it now.

    Seems to be OK:

    Of course I can only tell if it really works after upgrade is done. This Hyper-V host is a low end i5 laptop with VMs stored on a 5400 RPM spinner. Upgrade will take an hour, I know it from experience.
