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.

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.Find Windows 11 Version In ISO From Boot.wim
  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.
