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.
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" Deployment Image Servicing and Management tool Version: 10.0.19041.844 Details for image : E:\sources\install.wim Index : 1 Name : Windows 10 Home Description : Windows 10 Home Size : 14,803,056,683 bytes Index : 2 Name : Windows 10 Home Single Language Description : Windows 10 Home Single Language Size : 14,801,333,452 bytes Index : 3 Name : Windows 10 Education Description : Windows 10 Education Size : 15,059,155,772 bytes Index : 4 Name : Windows 10 Pro Description : Windows 10 Pro Size : 15,056,474,727 bytes Index : 5 Name : Windows 10 Pro Education Description : Windows 10 Pro Education Size : 15,059,094,190 bytes Index : 6 Name : Windows 10 Pro for Workstations Description : Windows 10 Pro for Workstations Size : 15,059,124,981 bytes The operation completed successfully.
Additionally, you get information about the Windows version (build) and available languages in the WIM/ESD file in the image with the index 5 (Windows 10 Pro), run the command below:
DISM /Get-WimInfo /WimFile:"E:\sources\install.wim" /index:5
In our example, we have found out that it is Windows 10 Professional (Version: 10.0.19041) with an English (en-US) language pack available in the installation image under index 5.
