If you want to see which version of Windows is contained in an ISO image, mount the image and run the following command in an elevated cmd/powershell window:
dism /Get-WimInfo /WimFile:A:sourcesboot.wimBe sure to change A: to the correct drive letter where the image is mounted. Also, combined x86/x64 ISO images will need to include the architecture before “sources”.
dism /Get-WimInfo /WimFile:A:x86sourcesboot.wim
dism /Get-WimInfo /WimFile:A:x64sourcesboot.wim
