    Since beginning of Windows Insider program we geeks have had a possibility to convert the ESD file of new upgrade build to an ISO image (tutorial). With it we could create DVD / USB install media to be used in clean, in-place and repair installs.

    Since Windows 10 Insider Build 14986 Microsoft has started to use new Unified Update Platform (UUP), which no longer offers the install.esd file (read more in this post). Through some registry modifications users can at least for now disable UUP and get ESD version of the build upgrade, but it seems that this option might not be available in the future.

    UUP is of course a positive change. It is differential, scanning user's existing Windows 10 installation only downloading and installing those system files that have changed. In ESD upgrade full Windows system (all system files and native applications) were replaced, with the same file or app version even in case the new build did not include a newer updated version. Regardless if a system file, component or application was updated, ESD upgrade replaced it. This caused download size to be bigger, in addition to longer time required for upgrade because full Windows was downloaded and everything overwritten with every upgrade.

    However, the possibility to create an ISO image is, has been and will be important to us Insiders. Microsoft has usually released an ISO when a build has been released to Insider Slow Ring, but we Fast Ring users do need an option to create our own install media.

    This tutorial will show how to do that, how to create an ISO image out of a UUP upgraded Windows 10.


    warning   Warning
    Notice please: When Windows Update has finished downloading the UUP upgrade, the files needed to make the ISO are stored in a subfolder in C:\Windows\SoftwareDistribution\Download.

    These files will in some cases be removed when upgrade is done. If you want to make an ISO for future needs, you have to do it before starting the upgrade process itself, after downloading the upgrade files but before clicking Restart now button!




     1: Download and install [B]UUPtoISO [/B]installer

    1.1)
    Download and run UUPtoISO_Setup.exe:

    download

    See credits and changelog at the end of tutorial: ChangeLog

    Notice that the installer is digitally signed by Designer Media Ltd, the owner of Ten Forums.

    Virus Total gives the installer almost all green, only one obscure AV / Malware system flagging it as a trojan. This is false positive, the installer is 100% safe:

    Follow on-screen instructions to finish setting up UUPtoISO

    1.4) You will find UUPtoISO in C:\UUPtoISO folder (default). To uninstall simply the delete the folder

    1.5)
    See Quick Start.pdf file in UUPtoISO folder for simple one page printable instructions


     2: Find correct UUP upgrade folder

    2.1)
    Open File Explorer, browse to C:\Windows\SoftwareDistribution\Download folder. It contains several subfolders named with a long hexadecimal string.

    2.2) In File Explorer, search for ext:esd to find all ESD files. Only one of the subfolders of C:\Windows\SoftwareDistribution\Download contains ESD files (extension .esd). So called express UUP upgrade has only one ESD file, canonical UUP upgrades can have 10+ ESD files. Regardless of how many ESD files your search finds, they are all stored in same subfolder, the one containing necessary files to make an ISO image

    Usually upgrades are differential (express) only containing one ESD file as in this example. Search for ESD files finds one file in folder staring with 5721f7. Right click it and select Open file location to open folder we need:

     3: Run UUPtoISO


    3.1) Run UUPtoISO, right click to automatically paste the UUP folder path copied in step 2.3, press Enter to start. Main menu will be shown:

    Note   Note
    There is a bug in builds 16193 and 16199 preventing user to select an option in a script like this tool. All that happens when you press 1, 2 or 3 as told above is a loud beep sound.

    If this happens to you, use the temporary fix posted in this post.

    I will remove this notice when Microsoft has fixed the bug in coming builds.

    3.3) The information option (#3) is useful to check that ISO will be what you expect:

    3.5) When done, ISO or install.wim can be found in folder where you installed UUPtoISO:

    That's it. You can now start upgrade or repair install using your ISO. To clean install Windows 10, ISO must first be burned to a DVD or USB flash drive (tutorial)

    Glad you reminded me to use RDP for my VMs - that made copying the files a snap from the VM to the local \UUPtoISO\UUPs folder.

    Generating my .ISO now.

    Just to check that I understood you correctly: You have 14986, UUP is not disabled in registry, no install.esd file in BT folder, 15002 upgrade downloaded and Windows is ready to start upgrade showing Restart now button, yet no upgrade files in C:\Windows\SoftwareDistribution\Downloads?

    Yes.

    When I checked it was updating to 15002 again. ESDs are there now!

    Also from other thread:

    I installed 14986 in Hyper-V using the ISO from Kari's Tutorial to make a bootable ISO using a WIM file.

    After the installing screen it continued on to the desktop WITHOUT asking for any choices. I then changed to*my MS Account and activated it.

    Downloading 15002 now.


    EDIT:

    I've successfully made an ISO of 15002 using*Kari's Tutorial. I the installed it in Hyper-V.

    Didn't really see much of a size difference. My UUP files came in at 2.9GB and the ESD is right around 3.0GB.
