It is possible to successfully install an operating system, providing you have the Product Key which is unique to the particular installation cd you are using. I have installed every version of Windows since Windows 95, including the 2000 and 2003 Servers, and I know that the critical issue is Activation and Verification - not the installation itself. You can use a single retail installation cd to install the Windows operating system on thousands of different machines, but alas, it is not as simple as that. The catch is that you must Activate your copy online within 30 days, or if not, you will then be unable to access your Desktop. It would be helpful, therefore, if some of the contributors here were to tell us if they managed to Activate and have their copy Verified by Microsoft.
I've installed two of these now. The first was lost because of a motherboard failure which wrecked the computer. That first disk wouldn't install on the new PC (I expected that) so I had to buy another. The second disk installed and authenticated perfectly well. The disk has all the correct holograms, and I'm confident it's genuine. As I remarked in another discussion, it doesn't come boxed (which you might have expected from the picture of it) but it does come with the product key attached. It's described as a 'full version', which is clearly not the same as a retail version, and I assume 'full' merely means it has all necessary components.
I have already made a comment about the importance of activation (it must be done within a month) because if it is not activated by the stipulated time, the user is locked out. This is the case with all versions of Windows despite the buyer having the correct product key and the ability to receive updates. Nobody has yet mentioned whether activation went smoothly - or not. Since I have now received the installation CD I can tell you that it must be used for a fresh install only. This product key cannot be used to legitimize a pirated version, or to upgrade an existing Windows 7 trial version. That means, all installed software, including post SP1 updates, will have to be re-installed. All documents and personal files on an existing installation will therefore need to be backed up elsewhere before the installation. I cannot comment further because I cannot install it without destroying my existing installation. It will not activate.
