Is it possible that we can know the version (i.e. OEM, Retail, or MSDN) given a windows 7 ISO file without installation?

Thank you

    Typically you can use the same iso for any key you have. The only difference is the license itself. – Ramhound Mar 22 '12 at 18:07
  • I've heard that an ISO for OEM will not accept Retail keys, and vice versa. I know that Anytime Upgrade won't let you go from a Retail to MSDN key, but I can't verify this for installations. – Melikoth Mar 22 '12 at 18:51
  • @Ramhound, I have confirmed that Windows 7 Key obtained from MSDN cannot work with ISO from here – q0987 Mar 22 '12 at 19:00

http://wiki.lunarsoft.net/wiki/Product_IDs is an source to determinate the version. The Retrieving your product ID or MPC section tells you how to find the ID on CDs, ISOs or running machines.


The information you need is to find that out is the Channel ID, which is part of the Product ID.

I found this link Windows 7 Channel ID portion od Product ID. It has a reference to the lunarsoft list mentioned by JohannesM, but mentioned that it contained outdated data. I'm not sure if this has been updated, as the post is a couple years old.

This link is in reference to Server 2003, but my help you find out more: How to determine the channel that your copy of Windows Server 2003 was obtained through


Based on this

Even though the install image “install.wim” in Windows 7 still contains four versions, one version is automatically installed determined by a file called “ei.cfg” in the “sources” directory on the install disk.
