Windows 10: UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files

How to: UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files


Note Microsoft has made some changes in the delivery system. UUP Dump working perfectly, allowing users to create Insider ISO images even when not opted in for Insider program, I see it pointless to update this tool.

Thanks for all our members and guests alike who have used the tool. It will be no longer updated.

See this tutorial instead: Windows Insider - Get Latest Fast Ring ISO image

Since beginning of 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. The tool also works with upgrade files downloaded with UUP Dump.


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!

See credits and changelog at the end of tutorial: ChangeLog

1: Download and install UUPtoISO installer
1.1) Download and run UUPtoISO_Setup.exe:

Download

The installer is at the moment not digitally signed. I am working for it. Anyway, it is totally safe as you can see at Virus Total, only two obscure AV tools flagging it. That is of course false positive, all other AV and malware tools flag it as safe. See by yourself: VirusTotal

1.2) Run installer, click More info when Windows Smart Screen tells file is not signed, click Run anyway:












1.3) Accept license, select where to install (default: C.\UUPtoISO):








Follow on-screen instructions to finish setting up UUPtoISO

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


Note Please do not forget to read the Credits & Quick Start PDF file in the folder where you installed UUPtoISO!

This PDF can also be separately downloaded: Credits & Quick Start.pdf

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:




In this example upgrade has been canonical containing 13 ESD files, all in same folder starting with a526e. Right click any of them and select Open file location:




2.3) Right click File Explorer addressbar, select Copy address to copy path of UUP folder to clipboard:





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:



3.2) In main menu select 1 to make an ISO, select 2 to make an install.wim file, select 3 to see information about which build, edition, bit and language version your upgrade is:






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:




Press any key to return to main menu

3.4) Press 1 or 2 depending on if you want to make an ISO image or install.wim ​file, the process starts. Be patient, it will take several minutes



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)

UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files  


Ok.......I'm doing something wrong. DL'd the new one from link in step 1.1, and keep getting this. Defender and MBAM.

 

UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files  

So basically I have already upgraded my system and I tried pointing the .exe tool to the Windows.old folder, and I get the error message that it couldn't find the esd file in the C:\Windows.old\Windows\SoftwareDistribution\Download folder. Am I doing something wrong? I think I am reading the quoted bullet point correctly.

Any help would be appreciated.

Thanks!

Well don't just stand there, man. Automate, automate.

 

UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files  


I DID IT!

Manually created esd files from the package folders:

STEP1: Processed ActionList.XML:




STEP2: Created a bunch of commands:




STEP3: Ran the commands one by one (sry no screenshot)

STEP4: Ran uup2iso as usually


RESULTS:

Converted these




to this




Created ISO




Mounting ISO




Looking at the Wim-files





Everything looks normal! Now we have to automate this! :-D

Yes, I will repack the tool, make new installer as soon as possible. The fix you provided, a simple change in one line of code, now makes it possible to make ISO images for x86, x64 and ARM.

I still can't give you any timeline, I have real life, too. In the meantime I would ask ARM users to see this post and download updated script to create ISO images: UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files - Page 104 - Installation Upgrade Tutorials
