Microsoft’s official Windows 11/10 Media Creation Tool lets you download the latest version of Windows 11/10 ISO. If you want to perform a clean installation of Windows 10, you should use the latest ISO.

There are times when you find a Windows 11/10 ISO on your PC, but you are not sure about that ISO’s build number. How to check the build number, version info, and architecture of Windows 10 ISO without installing it?

Luckily, this risewindows post will guide you on an easy way to figure out the build number and another detail about Windows 11/10 ISO file. You need to mount the ISO file and execute a command to know the build number and other details of the ISO file.

How to Find Windows 11/10 Version Number in ISO or USB Drive?

To view the details from an ISO file, you need to do the following steps:-

Step 1. First, connect the bootable USB flash drive to the PC or mount an ISO image file to a virtual drive.

Then, double-click on an ISO file to mount it. If some other software is associated by default with ISO files, please perform right-click on the ISO image and select the Mount option from the context menu.

Step 2. Now open the File Explorer by pressing Windows + [/keybt]E[/keybt] hotkey or using other methods and then navigate to the virtual drive created for your ISO file, or open the connected USB drive letter.

Step 3. After that, open the sources folder and find the file named install.wim, install. swm or install. esd.

Step 4. Please Note down the drive letter assigned to the ISO file or USB drive in File Explorer from the address bar. In my case, it is an “F” drive. So, open Command Prompt as administrator. For that, open the Run dialog box by pressing Windows + [/keybt]R[/keybt] keys from the keyboard. Then, type cmd in the Run box and press Ctrl + Shift + Enter from the keyboard.

Step 5. Next, on the prompt, type the following and hit Enter from the keyboard:-

dism /Get-WimInfo /WimFile:X:\sources\install.wim

Quick Note: In the above command, replace “X” with your drive letter. Also, replace and install. wim with the installation. esd or install.swm, if the install file is different than mine.

After executing the above command, the DISM tool will show the details of the Windows 11/10 version contained in the ISO file. You will also see the index number of all editions in the ISO image file. If you want to view more details for a specific OS edition, note down its index number and issue the following command:-

dism /Get-WimInfo /WimFile:X:\sources\install.wim /index:<Index number>

Quick Note: Replace X with the drive letter for ISO/USB flash drive on your PC. Now change the <Index number> from the number of indexes you noted in the above output.

For instance, in my case dism /Get-WimInfo /WimFile:F:\sources\install.wim /index:1 shows details for the Windows 11 Pro edition in the install.wim file.

So, you can view Windows 11/10 edition, architecture, Version, ServicePack, and date of creation of ISO file using the above command.

That’s it for the article.

I hope this post will be helpful to you.
