How to Find out Windows ISO information

If you have downloaded a Windows 8 / 8.1 or Windows 10 ISO from Microsoft and have forgotten which edition it was, or which service pack or feature release is in the ISO, there is a useful DISM command that I can use would like to go into more detail.

In order to find out this information or the edition, the first thing to do is to mount the ISO. You do this by right-clicking on the iso and clicking on "Provide". Then another drive should appear in Windows Explorer under "This PC", which is usually represented as a DVD drive.

This tutorial is suitable for Windows 10 2004 and above, 1909, 1903, 1809.

ISO information about the properties

The following methods can now be used to find out which product version / build version is available in the ISO:

  • In the source folder the:
    • install.wim
    • install.esd
    • setup.exe (not always meaningful)

with a right-click on "Properties" and under Details the product version is then also displayed.

Find out ISO information about DISM

  • Open the command prompt by searching the taskbar
    • Or press Windows key + X and start the command prompt Powershell and command prompt swap Windows 10
  • With the command dism / Get-WimInfo /WimFile:F:\sources\install.esd / index: 1 for an install.esd
  • With the command dism / Get-WimInfo /WimFile:F:\sources\install.wim / index: 1 for an install.wim
    • Note: The drive letter E is used as an example only. You have to replace the letter with your own drive letter of the ISO file. You can also read out the product version, as well as the edition and much more.

As an example I am using a Windows 10 Pro ISO.

Find out all contained versions in the ISO

There are multiple versions in the Windows 10 ISO, so the key decides which version is installed. If you want to check which ones can be found in the ISO index, you only need PowerShell

  • Right-click the ISO -> Provide
  • Windows key + X PowerShell (start administrator
    • Or enter PowerShell in the search on the taskbar and start it with pressed Ctrl + Shift key
  • Type dism / get-imageinfo /imagefile:F:\Sources\install.wim and press Enter
    • Note F is for the drive. This letter needs to be adjusted.
    • Note 2: If you have an ISO with an Install.esd, this must also be adapted.

For example, the following is now displayed:

  • Index 1: Windows 10 Home
  • Index 2: Windows 10 Pro
  • Index 3: Windows 10 Lean
  • Index 4: Windows 10 Home N and so on

Find out versions of install.wim and boot.wim with DISM-GUI

With the small DISM-GUI tool, it is also possible to display the information from install.wim and boot.wim without having to enter commands in the command prompt.

  • To do this, the ISO must be made available by right-clicking
  • Start DISM-GUI and click menu 2
  • Now click on Info and select the path to the provided ISO
    • Open the sources folder and select install.wim or install.esd or boot.wim

The information about which Windows 10 version or boot version is included is displayed immediately.

Find out details of the boot.wim

These details (index) are also contained in Boot.wim. If you want to find out what is included here, too, use this command in PowerShell:

  • dism / get-imageinfo /imagefile:F:\sources\boot.wim
  • Note L is for the drive. This letter needs to be adjusted.

Now, for example, is displayed

  • Index 1: Microsoft Windows PE
  • Index 2: Microsoft Windows Setup

Call up information via the context menu

If you have to do with an install.wim, install.esd, or * .cab file, you can call up the information directly via the context menu.
