Trouble finding W10 21H2 ISO

garlin said:
abbodi86, I finished writing a new MCT wrapper which uses /selfhost.
When comparing your list against AveYo's script, I noticed a discrepancy for W10 21H2. Is there a specific reason for Mar 2022 vs. RTM?

More recent version is better
although 19044.1586 cab is dated Mar 2022, it was not actually released until late Nov 2022
AveYo didn't get the chance to include it in his script (before he went AWOL)
 
MCTWrapper downloads an older version of Media Creation Tool from MS, and runs in self-hosted mode. Without self-hosting, it doesn't find the matching version of the old ISO.

And how do I run that script? Do I need to download anything else?

Just run uup_download_windows.cmd as administrator and it will download everything and generate the ISO (if you chose it previously on the website).
It takes a long time on my PC to finish the job, but eventually it will generate your ISO.
 
uup_download_windows.cmd can run from Explorer or a normal CMD, it will ask permission to run as Admin in a new window.
 
I figured it out and I downloaded the ISO creation script from the UUP dump and I'm downloading the ISO now thanks guys. Is it OK if I just selected Pro?
 
You can personalize your downloaded editions from UUP dump's Choose Edition page. Whatever you want.
 
Where does the script put the actual ISO after running? I've tried going through all the folders. I would like to put it somewhere I can access it easily such as my desktop.
 
When the script finishes with a "Press 0 to exit" message, the ISO is in the script folder.

I'll save you the work of Steps 1. thru 3B.
Code: 
C:\Users\GARLIN\Downloads\MediaTools>MCTWrapper.bat
Please specify a MCT version:
W11_23H2
W11_22H2
W11_21H2
W10_22H2
W10_21H2
W10_21H1
W10_20H2
W10_2004
W10_1909
W10_1903
W10_1809
W10_1803
Code: 
MCTWrapper.bat W10_21H2
MCTWrapper.bat W10_21H2 /Retail /MediaLangCode en-US /MediaArch x64 /MediaEdition Enterprise

This script downloads the right MediaCreationTool.exe (if the file isn't found), and runs self-hosted. You can pass along MCT command line options to skip any language, architecture and edition prompts. Multiple copies of MCT can exist side by side, because the script knows where to find the correct products.cab.

If you're asked for a product key, use one of the generic KMS client keys. Key Management Services (KMS) client activation and product keys
From the above example, Enterprise edition requires NPPR9-FWDCX-D2C8J-H872K-2YT43.

Create a local ISO file (since you're going to use NTLite to edit the image). Continue to Step 3G.

UPDATE 2023-07-21: MS removed 1803's MCT, switched to the Internet Archive's copy
UPDATE 2023-11-16: Added 23H2
UPDATE 2023-12-21: Updated 23H2 (22631.2861)

This is fantastic! Hoping you will get it up on github...

Noticed only the latest 23H2 is available, and not the previous 23H2. I need the previous one because there is a bug in the current one causing issues with Autopilot.

The only other 23H2 release available from MCT is 22631.2715.

Replace the 23H2 lines with:
Code: 
    'W11_23H2' = @(
        'https://download.microsoft.com/download/e/c/d/ecd532eb-bed0-465a-9b7a-330066bec3ce/MediaCreationTool_Win11_23H2.exe'
        'https://download.microsoft.com/download/e/8/6/e86b4c6f-4ae8-40df-b983-3de63ea9502d/products_win11_202311109.cab'
    )
 
Not trying to downplay MCTWrapper or any other method, just trying to put more info out there. Also, if anyone knows why this info might be incorrect, Please let me know as I am in the middle of this ntLite upgrade from a Win 7 System.

I a NTLite Newbie (NOT a tech Newbie). I know I'm late to the party but I found a 21H2 download from Internet Archive / Way-back Machine and the Hash checks out to be a Legit MS Download. I used the following information that I will copy/paste below. I followed the original posters source plus dug a little myself to verify MS Hash. Like I said, the Hash checks out but do your own research into this. It is a SLOW download, took about 20min. (But I'm from the dial-up days, so I don't mind the wait).


Scource of Origainal Post (not trying to break rules if link is not allowed, just trying to give all info for reader to research yourself):
https://superuser.com/questions/1790347/rufus-and-previous-windows-10-versions

Rufus doesn't have their own hosting for those ISO downloads, they always pull it from the official releases download links. Since Microsoft recently decided to remove their official download links for past versions of Windows, Rufus also doesn't have them anymore.
The best way to download now an ISO for Windows 10 21H2 would be to find somewhere online that has the ISO to download (there are links for it all over) and once downloaded verify the file hash that it's indeed the untouched ISO of Windows 10 21H2.
Good Luck Everyone.

Mod Note: Sharing links to non-official ISO sources is against forum rules.

The drawback of searching the Internet Archive (Wayback Machine) is you can't always find every Windows release in all languages.
Something like a W10 21H2 x64 English (US) can be easily found, but your success rate drops off for other languages.

Your organization's IT policy may not accept ISO's not sourced from a MS download, even if the hashes agree.

This is why the MCTWrapper and W10_11aria2ESD scripts are provided, for those groups who must document how they got their ISO's. The source code for both of them aren't too difficult to audit.

Finally, Wayback Machine is pitifully slow.

Yes, you are 100% correct. There are many factors one should consider based on their own situation. However, in my case the ISO will be used on a personal level and this was a good solution for me.
