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. – ItsNotAboutTheName 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. – ItsNotAboutTheName 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

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

All those answers are good except that you can simply open the ISO with 7-Zip and in the "sources" folder open, inside of 7-Zip, the file "install.wim". In the XML file mentioned, when opened, you will find exactly what "SPLEVEL" you have regardless of what the OS "NAME" is. No need to open "boot.wim" or mount it for that matter.

Cheers
