Regeln » How to Activate Windows 7 by Phone?

Genuine Window is a recurring process that checks your product key to ensure it's being used with the hardware it was paired with during activation. If the product key is found to be non-genuine, or not valid, it's likely that the product key is either being used on another computer or is counterfeit. Try doing the Diagnostics and Validate Windows options. For more information about genuine Windows, go to the genuine Windows website for FAQ.
