Darren Pauli writes at the Register that researchers who scanned 900 Windows libraries have uncovered a variety of security functions that were updated in Windows 8 but not in Windows 7. Researcher Moti Joseph speculates Microsoft had not applied fixes to Win 7 to save money. "Why is it that Microsoft inserted a safe function into Windows 8 [but not] Windows 7? The answer is money. Microsoft does not want to waste development time on older operating systems ... and they want people to move to higher operating systems," Joseph said in a presentation at the Troopers14 conference.
Joseph along with Marion Marschalek developed a diffing (comparison) tool dubbed DiffRay which compares Windows 8 with 7, and logs any safe functions absent in the older platform. In a demonstration of DiffRay, the researchers found four missing safe functions in Windows 7 that were present in 8 (Youtube). Future work will extend DiffRay's capabilities to find potential vulnerabilities in Windows 8.1 (PDF), add intelligence to trace input values for functions and incorporate more intelligent signatures used to find potential holes. "If we get one zero-day from this project, it's worth it," says Joseph.

To just dump microsoft. Don't use anything output by Redmond, ever. When you do that, the non-security of windows becomes a non-issue for you.
Remember, microsofts true reason for being is to get you to pay them more money. If you are tired of handing over your money to them, then just quit using their stuff - problem solved.
