    OK, so I never did this before. Is everyone saying that if my ESDtoISO is June 15th and I select option 1 I will be OK and have the install/repair functions working?

    Thank you all.
    Yes, if it is dated that or after (because, depending upon your set up, you might be looking at the created or modified date).

    Basically, if it gives you 3 options, ESD or WIM .ISO and ESD info, you should be good, because that is the script as edited by Kari.

    If you're in any doubt at all about the date, get a fresh copy of the ESDtoISO per post #1. It only takes a couple minutes, and you'll be safe. WIM format (option 1) is needed if you do any DISM repair work. ESD format will not work. The difference in size is only about 600-800MB.

    Thank you both. I did get the file and the June 15 date is in the unzipped archive so I should be good. I guess the safest thing is to select option 1. This should make a bootable iso where I can install on a new system. I hope this is correct.

    Both will allow you to install. The WIM-based .ISO allows you to customize the disc prior to installation using the native windows utility DISM in a fashion that most people do not use (think in terms of manually doing the work of what tools like NT-Lite do for you).

    If you plan on installing normally, or installing and making changes after installation, the ESD-based .ISO will work perfectly fine.

    Well, it failed to work. Even option 3 runs but closes the window before I can read it. I thought there was a tip to disable av software, so I will try again...

    PLEASE NOTICE:

    The tool and the method in this tutorial both work without issues with ESD file of the latest Insider Build 14971 released earlier today

    Upgrading Windows 10 - ESD or UUP?


    information   Information
    As of build 14986, released to Fast Ring Insiders this week, Microsoft has changed the way upgrades will be delivered. The new method is called Unified Update Platform (UUP). More information on Microsoft blog: Introducing Unified Update Platform (UUP) - Windows Experience BlogWindows Experience Blog

    UUP downloads and delivers an upgrade as a differential upgrade. All geeks know what a differential backup means, it simply backs up only those files changed since the last full backup. The same principle applies to differential upgrade: Windows Update will only download and install those system files changed since the current installed build.

    This will make the downloaded upgrade packages smaller and will most probably also reduce the time needed for upgrade.

    Let's see the main differences in these two methods, in a very simplified way.

    ESD method:

    Windows Update downloads files for a full Windows 10 setup. This includes everything to perform a clean install of Windows or replace everything in in-place upgrade and repair install, containing all native Windows desktop and UWP apps, all system files and folders, dynamic libraries, absolutely everything. It also contains the install.esd file which can be converted to an ISO image, giving user a full Windows install media.

    When a user starts upgrade, all Windows system elements and components will be replaced. Mail app will be reinstalled, as will PowerShell and Command Prompt, Notepad and Windows Media Player, and so on, regardless if these applications have been changed (new version) since the current build which will be upgraded. All dynamic libraries will be replaced and reinstalled, all Windows components will be reinstalled.

    This of course means unnecessary downloads, file replacements and application reinstalls. A simple example: The Weather app version did not change in build 14971, compared to build 14965. In both of these builds the app version is 4.17.74.0. However, as the ESD method does a full in-place upgrade replacing / overwriting all Windows system components, Weather app will be reinstalled replacing the same version of itself.

    UUP method:

    When Windows Update finds a new build, it will check the user's current build application / dynamic library / other system file versions and download only those Windows components that have been changed. Using the above Weather app example it would not be downloaded and installed if the app version in new upgrade build is the same as that user has currently installed.

    OK, leaving Weather app out of upgrade download does not save too many bits and bytes, but if you multiply that with the number of Windows desktop and UWP apps, dynamic libraries and other Windows system components not needing an upgrade, it will become quite clear that depending on upgrade, the download size will be smaller and because there's less to overwrite also the time needed for upgrade will be reduced.

    By default UUP is enabled.

    Tip   Tip
    If having a possibility to make an ISO image and create your own install media weighs more than reduced download size, you must manually disable UUP in Windows registry.

    Both of the following DWORDs have by default value 1 (UUP enabled). You must change both values to 0 (UUP disabled) to keep getting the ESD file and full build download:

    Key: HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>Windows>CurrentVersion>WindowsUpdate>Orchestrator
    DWORD: EnableUUPScan

    Key: HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>WindowsUpdate
    DWORD: SupportsUUP

    These DWORDS must have the same value, 1 for UUP enabled, 0 for UUP disabled.

    If you want to you can also use following registry scripts to switch to ESD upgrade or UUP upgrade. Just download the one you need and run it to change relevant values in registry:



    Thanks to esteemed fellow geek @f14tomcat for these registry scripts :)

    If you have already upgraded when UUP was enabled, you do not have and can't get the ESD file. Do the above registry changes before next build upgrade to assure you will get ESD file.

    If your upgrade has been downloaded and prepared but you have not yet clicked Restart now button in Windows Update to start upgrade, you can do the following to redownload upgrade and get the ESD file:
    - Edit the registry as told above
    - Open Disk Clean-up > Clean up system files
    - Select Temporary Windows installation files, click OK:
    ESD to ISO - Create Bootable ISO from Windows 10 ESD File-image.png

    - Wait until clean up is done
    - In Settings app > Windows Update, click Restart now
    - Windows will now restart for upgrade but as no upgrade files will be found, it boots back to desktop
    - Now let Windows Update to download the upgrade again, this time it will be the full upgrade and include the ESD file

    Thanks for fellow member @Bat 1 for registry tip.
