Find Windows 11 Version in ISO File or USB Drive

In this post, we will learn how to find Windows 11 version in ISO file or on a USB drive. Also, you will be able to quickly see what Windows 11 edition, build number, language and other details an ISO image contains.

Windows 11 ISO images downloaded from the official Microsoft servers may come with meaningful names, but the name tag often do not include important details. For example, a name like Windows11_English_x64.iso gives you no clue if it comes with Pro, Home, or any other edition. You can't also say at a glance what is the build number inside the ISO.

In this case, you have need to use the DISM tool. It allows you to get all the details of the Windows 11 version included in the ISO file with ease.

How to Find Windows 11 Version in ISO or USB Drive

To find what Windows 11 version ISO file contains, do the following.

1. Insert your bootable USB stick, or double-click your ISO file in File Explorer to mount it. If some other software is associated by default with ISO files, the right-click your file and select Mount from the context menu.
2. In File Explorer, navigate to the virtual drive created for your ISO file, or open the connected USB drive letter.
3. Open the "sources" folder and find the largest file by size, named install.wim or install.esd.
4. Now look at the address bar and note down the drive letter assigned to the ISO file or USB drive in File Explorer. In my case it is the G: drive.
5. Open Windows Terminal as Administrator by pressing Win + X and selecting Windows Terminal (Admin).
6. In the console window, type dism /Get-WimInfo /WimFile:G:\sources\install.wim. Replace G: with your drive letter. Replace install.wim with install.esd if you have the latter one.
7. The DISM tool will show all the details about the Windows 11 version contained in the ISO file, including version, bitness (architecture), language, its build number, and so on. Also, it will list all the edition indexes available in the OS image.
8. To view details for a specific OS edition, note down its index (see the screenshot), and issue the command dism /Get-WimInfo /WimFile:G:\sources\install.wim /index:<Index value>. For example, in my case dism /Get-WimInfo /WimFile:G:\sources\install.wim /index:2 shows details for the Pro edition in the install.wim file.

Here is an example DISM output for the Windows 11 Insider Preview ISO image.

Checking Windows 11 Install.esd file on Windows 7

If you are running now-unsupported Windows 7, you will run into a trouble checking the contents of the Install.esd file. The built-in DISM version in Windows 7 doesn't recognize *.esd files. It will show you the following error message.

An attempt was made to load a program with an incorrect format.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

However, it is easy to bypass this limitation. Instead of install.esd, use the boot.wim file you can find in the \sources directory.

To check Windows 11 version contained in an ISO file in Windows 7, do the following.

1. Open an elevated Windows Terminal; for that press Win+X and select Windows Terminal (Admin).
2. Type the following command: dism /Get-WimInfo /WimFile:G:\sources\boot.wim /index:1. Replace G: with the actual drive letter of your mounted ISO file or connected USB drive.
3. The DISM tool will finally display all the details for the boot.wim file that will give you a clear idea of what is the OS version you have.

That's all about how to find the Windows 11 version in ISO file.
