You are purchasing a genuine, never used, never activated, Windows 7 Professional retail product key. (I also have Ultimate Retail and Professional N Keys, please let meknow which one you want)
It will work on 32 bit or 64 bit operating systems. This is a unique key from MS and the buyer will have the only copy of that key. It can be used on only one computer, but can be used multiple times on that same computer.
It will not work on a beta or RC versions. Since this is legitimate, please do not try to use it on more than one computer as you may be blocked.
This is ONLY for the key, not the actual software. Once payment has been completed,
I will email the key to the buyers Paypal email address within a few minutes to a few hours, unless its overnight or the weekend.
