I've 6 different Windows 8.1 64-bit / 32-bit installation .iso images. All of the 6 images are untouched and officially released by Microsoft. How could I identify the basic information of each .iso image? The basic information that I need to know how identify: (Type of image: is RTM, RTL, VL, or OEM), (Release Date), (Image Version), (Update / Rollup Updates included), and (Servicepack version). I've searched for how to do that, but unfortunately none of the methods I found worked for all the information I needed.

Run Dism /Get-WimInfo /WimFile:"E:\sources\install.wim" to see which SKUs are included in the WIM. Now open the idwbinfo.txt on the DVD/ISO under sources, here you see if it is 32 or 64Bit and if it is a debug (checked) or the normal (retail) version.

  • I still can't get these attributes: Release Date: ex. 10/17/2013, RTM BUILD: ex. 6.3.9600.16384.WINBLUE_RTM.130821-1623, and ROLLUP UPDATE BUILD: ex. 9600.16404.WINBLUE_GDR.130913-2141. What I successfully able to get: Type of image (identified from idwbinfo.txt), and Servicepack version

  • the only way to get this is selecting the properties of a file like setup.exe and look at the file information. Apr 26, 2015 at 7:23
  • I'm now successfully able to get the RTM BUILD via the setup.exe file information. How about the Release Date, ROLLUP UPDATE BUILD?

  • for new ISOs which have rollups, the setup.exe also gets updated. Apr 27, 2015 at 17:29
  • How could I get the ROLLUP UPDATE BUILD number from the setup.exe? I've tried and I can get the RTM BUILD number only!!
