How to determine Windows version from ISO file

You can gather Windows information from ISO file using DISM in two easy steps:

  1. Mount the ISO file. Note the drive letter;
  2. Open elevated command prompt and start:
    dism /Get-WimInfo /WimFile:F:\sources\install.wim /index:1

Replace F with the drive letter of mounted ISO file.

The output will be similar to this one (I’ve highlighted interesting parts):
