Windows 10 will be a free upgrade for “genuine and non-genuine” users
 

Speaking to Reuters from the WinHEC conference in China, Microsoft's operating system chief Terry Myerson said, "We are upgrading all qualified PCs, genuine and non-genuine, to Windows 10." This means that everyone running Windows 7 or 8.1, irrespective of whether you pirated the operating system or not, will be allowed to upgrade to a legitimate version of Windows 10.
