When the OS is installed and you try to see what is already installed:

-you can open the file ../Windows/System32/license.rtf with Wordpad. Guess what, it tells you EXACTLY what system is installed. On that same drive above, this file said “WINDOWS 8 PRO”.

When you know the OS version but you don’t know the architecture (x86/x64):

32-bit versions of Windows will only include a single Program Files folder, while the two folders you see above will be present on any 64-bit system. The Program Files (x86) folder is where applications that are meant to run on 32-bit systems are installed. The main Program Files folder is where all 64-bit applications reside.

When you have an installation DVD without knowing the OS, the build version or the language:

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.


Open 7zip and go to Windows.iso\sources\boot.wim\[1].xml

n there you can find the exact build information similar to this:

<PRODUCTNAME>Microsoft® Windows® Operating System</PRODUCTNAME>


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