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

Version number? Do you mean architecture (32-bit/64-bit), service pack (RTM/SP1), edition (Starter/Home Basic/Home Premium/Professional/Enterprise/Ultimate) or the version number, as in build number (note Windows 7 is always 6.1, with varying build numbers depending on service pack)? –  Bob Jun 30 '12 at 13:46
    
@Bob All of them. In particular build number –  PHPst Jun 30 '12 at 16:15

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:

<WINDOWS>
<ARCH>0</ARCH>
<PRODUCTNAME>Microsoft® Windows® Operating System</PRODUCTNAME>
<EDITIONID>WindowsPE</EDITIONID>
<INSTALLATIONTYPE>WindowsPE</INSTALLATIONTYPE>
<PRODUCTTYPE>WinNT</PRODUCTTYPE>
<PRODUCTSUITE/><LANGUAGES>
<LANGUAGE>en-US</LANGUAGE>
<DEFAULT>en-US</DEFAULT></LANGUAGES>
<VERSION><MAJOR>6</MAJOR><MINOR>1</MINOR><BUILD>7601</BUILD><SPBUILD>17514</SPBUILD><SPLEVEL>1</SPLEVEL></VERSION><SYSTEMROOT>WINDOWS</SYSTEMROOT></WINDOWS>

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

This shows the architecture. However, it does not show the build number, service pack level or edition when I attempted it on my Windows 7 DVD. Depending on what @Reza meant by version number, this may or may not answer the question (and if architecture was meant, then this is a duplicate question). –  Bob Jun 30 '12 at 13:48
    
Read the update please. –  Nima Jun 30 '12 at 13:53
    
Nice! However, it would be better if you could describe how to open boot.wim. So far, I've attempted to mount it with dism, which does not reveal a [1].xml anywhere. –  Bob Jun 30 '12 at 14:02
    
I used 7-zip, but there are several alternatives. –  Nima Jun 30 '12 at 14:05
    
Ah, you extracted the image itself rather than mounting it... To clarify for others, [1].xml is actually metadata of the boot.wim image that you can see if you extract it with something like 7-Zip, but not if you mount it with something like dism (and maybe ImageX). –  Bob Jun 30 '12 at 14:24

Nima is onto something, however newer images can have multiple indexes, so you get more details by adding /index:1 or equivalent. See here for a Windows 8 example (from cmd as Administrator):

C:\WINDOWS\system32>dism /Get-WimInfo /WimFile:D:\sources\boot.wim

Deployment Image Servicing and Management tool
Version: 6.3.9600.16384

Details for image : D:\sources\boot.wim

Index : 1
Name : Microsoft Windows PE (x64)

Index : 2
Name : Microsoft Windows Setup (x64)
Description : Microsoft Windows Setup (x64)
Size : 1,264,587,270 bytes

The operation completed successfully.

Windows PE is the installation environment, so I guess here we really want to look at index 2 instead.

C:\WINDOWS\system32>dism /Get-WimInfo /WimFile:D:\sources\boot.wim /index:2
