Version number of Windows 7 from its image (iso,..)

How find out version number of Windows 7 from its DVD image before installing it?

Answer

Assuming you can mount the image, run cmd as administrator and type:

dism /Get-WimInfo /WimFile:A:\sources\boot.wim

A is your iso mountpoint.

or just extract the boot.wim file to somewhere and use its location in the command above.

Update: If you open boot.wim, there is an xml file usually called [1].xml. in there you can find the exact build information similar to this:

0
Microsoft® Windows® Operating System
WindowsPE
WindowsPE
WinNT

en-US
617601175141WINDOWS

The tag is what tells you the built version. for above example: V 6.1.7601 SP1.17514
