Hi everybody. I seek some help as of I am very confused. My Windows now says that "This copy of Windows is not genuine" and that is not true! I bought my Windows 7 at the very day it was released in a retail store! And i have never had any trouble with it before, it has always been saying that it was a true and registered version of Windows. Please i don't know what to do, do any one have an idea of why it is saying this?
