Windows 7 - Key Product for win 7

Dear all,

First, thanks a lot for this fantastic forum and I hope find help for my problem here!
I have just simple question about the key product for windows 7. Actually, I have already downloaded win 7 pro (iso file) from MSDN, but I don't find the key product to activated it!
I burned the iso file to a DVD and installed and it works but without activation and this will not continue after a while. When I explore the iso files, I don't find information about key or serail number!
Please, somebody has any idea about this issue? Where or how can I find the key product for windows 7 downloaded from MSDN server?

Thank you for help

You can get the product key from MSDN.

If you obtained it via a TechNet license download, then the key is obtained from the link next to the download link - see screen capture.

Log onto MSDN Subscriber Downloads site. From the page where you download the actual products from, you should find a couple of columns....one of which is a Keys column and a link which says View.

When you click on View, it will expand the window and will either show the key if you have previously retrieved it, or you can click on Get key and it will generate a key for you.

Edit: The picture posted directly above this is pretty much the same thing that MSDN uses and does.

Wow ! How stupid I'm !
Thank you very much guys!
You are the Kings !
