While this technology is only designed to display the “ This copy of Windows is not genuine” message to users using pirated copies of Windows 7, it sometimes slips up and displays the message to Windows 7 users who own completely legitimate copies of Windows 7. This is quite similar to the “ You may have been a victim of software counterfeiting” message that would appear on computers running on Windows XP should their copies of the OS be detected as pirated copies. If, in any case, Windows 7 would determine that a specific copy of the OS was not genuine, it would replace the user’s desktop wallpaper with a blank black background with a message stating “ This copy of Windows is not genuine” along with the version and build of the Windows OS installed on the computer in question. With the KB971033 update to the Windows 7 Operating System, Microsoft made the then-latest version of the Windows OS capable of determining whether or not a copy of Windows 7 was genuine and the real deal.
