Windows 10 ISO

Is there a way to find out what build the MS MCT ISO is?

If you right-click the iso and select mount, the iso will be assigned a drive letter.

For example lets say you mount it and it is assigned drive letter G

From an elevated command prompt. type:

Dism /Get-WimInfo /WimFile:G:\sources\install.esd /index:1

Press Enter and the information will be displayed.

Note: Some iso will have install.wim, rather than install.esd in the Sources folder. If that is the case for your iso file, then use this command instead:

Dism /Get-WimInfo /WimFile:G:\sources\install.wim /index:1

Thanks Reg....but i meant, how to check what build the ISO download is.....before downloading it.

 

[Regedit32]

Ahh.

To be honest I've never thought about that.

Obviously the tool downloads the latest available update, but as you have noted it does not tell you the build number before you download it.

Even the Catalog or KB page for the update makes no mention of the build number.

You probably know about this site. Not sure if it will really help you query though

Forgot about that webpage.

It's a bit of a pain running back and forth between pages, but it does provide the information OP wants.

Question though: Is that page updated the same day they release the build to the Creator tool for downloading?

This is says what the current build is, not what the ISO will be.
The latest ISO I have made last weekend was 1903.18362.356 (September 2019)

 

[Bighorn]

I downloaded yesterday using the MCT and got Build 18362.356.

 

[Comp Cmndo]

Latest MCT build is 18362.418.

...but that has nothing to do with the build of the ISO it will create. That is determined by the Products.xml file that it downloads each time it is run.

<?xml version="1.0" encoding="UTF-8"?>
<MCT>
<Catalogs>
<Catalog version="1.3">
<PublishedMedia id="" release="">
<Files>
<File id="">
<FileName>18363.418.191007-0143.19h2_release_svc_refresh_CLIENTCHINA_RET_x64FRE_zh-cn.esd</FileName>

There are two ways to check the build it will install before that. The one I used is to run the MCT as far as the licensing notice, then read the Products.xml found in C:\$Windows.~WS\Sources.

Yes, the above build that "Comp Cmndois" is quoting is the v1903 - OS 18362.418 which is the "October 8, 2019—KB4517389 (OS Build 18362.418)" and the MCT is still the same when I downloaded it on the 12 Dec 2019. The .iso files never have the latest versions and/or the latest OS builds when you download them. You still have to run "Windows Update" to get windows to be updated to the latest updates. The latest MCT .iso windows installation files are 5 updates behind the current v1909 "December 10, 2019—KB4530684 (OS Builds 18362.535 and 18363.535)".

If wanting to know what the MCT process installs disconnect from the Internet before running it, check the actual Version and Build numbers. Then reconnect to the Internet to update to the latest offering.

Everyone can get it from Microsoft free.

We know that. That was not the question. The question was which version the Media Creation Tool builds.

 

[Bighorn]

What I got Saturday was Version 1909 Build 18363.418, clean installed then updated to Build 18363.535.

 

[Tim Locke]

I wonder if then a week today ( or maybe 2 weeks today ) that 535 will download and update to whatever Januaries build is?

Is there a way to find out what build the MS MCT ISO is?

Firstly this depends on what version you have installed. There is more than one version build of Windows 10.

 

[Bighorn]

I always download the "for another computer" choice and get the Both [x86 and x64], doesn't depend upon the version installed on the machine in use.

 

[Snuffy]

That still does not answer his question.

Is there a way to find out what build the MS MCT ISO is?

and he also does not want to DL to find out...
