How to Know the Windows Version of an ISO Image File

In some cases, you’ve an ISO image file Windows.iso. But you don’t know which Windows versions or edition are stored in ISO files. If an ISO file name doesn’t contain a version and a build, it is hard to know which version of Windows is inside.

Determine Windows version in an ISO file

1. First, right click on the image file then Mount it into your computer.

2. You will see a window with the contents of the virtual disk a Windows ISO image is mounted to. Open the Sources directory and find an installation file with a Windows image. The file is called install and may have one of the following extensions: install.wim, install.esd or install.swm.

3. Press and hold the Shift key then right-click install.xxx and copy the path to the file by selecting Copy as path.

4. Open the command prompt as administrator and run the following command (use the path from the clipboard as a file path):

DISM /Get-WimInfo /WimFile:"E:\sources\install.wim"

5. You will see a list of editions (Education, Home, Enterprise, Pro, etc.) available in this Windows ISO image. In our example, this iso file has 6 different Windows editions. Each edition has an index you can use to get detailed information about the image.

C:\Windows\system32>DISM /Get-WimInfo /WimFile:"E:\sources\install.wim"
