KB4012218 and KB4012219 are patches with CPU detection

If you recently bought a new PC or assembled one yourself with a new CPU and decided to install Windows 7 or Windows 8.1 on it, you will not be able to update these operating systems. Microsoft is not going to deliver updates for you any more. This was recently announced. A newly released set of patches brings the CPU detection feature to Windows 7 and Windows 8.1.
