The file contains both the OEM activation certificate and the product key.
In a recent blog post, however, Genuine Windows director Alex Kochis stated that the product key is indeed valid but will only activate PCs from the original manufacturer it has been given to.<ref>{{cite web|url = http://blogs.msdn.com/wga/archive/2009/07/30/windows-7-oem-product-key-leak.aspx | title = Windows 7 OEM Product Key Leak | author = Alex Kochis}}</ref> Kochis went on to say that anti-piracy technologies built into the operating system would detect copies activated with the leaked OEM certificate and product key as non-genuine and would notify the customer that they are running a possibly counterfeit copy of Windows.
It has already been proven however, that the product key and certificate are able to activate Windows 7 build 7600 on many different PC brands.<ref name="OEMLeak">{{cite web| url = http://scforum.info/index.php/topic,3057.msg6900.html | title = Windows 7 Ultimate hacked with OEM master key (boot.wim, .xrm-ms, OEM-SLP key) | author = Samker}}</ref> It is not clear however, if copies of Windows installed this way will pass Microsoft's Genuine Advantage check if the product key is blacklisted. If so, OEMs will be forced to recollect PCs manufactured, installed and activated with the key and install different keys.
