Why You Can’t Continue On WS2003

So what’s the big deal if you’re running a machine with no patches? Well, as AppZero emphasizes, it’s just a terrible idea.
Even though the operating system was released 12 years ago, there are still quite a number of patches that are regularly released. In 2013, Microsoft released 37 critical patches, and 26 more patches in 2014. Without those patches, WS2003 servers will become both vulnerable and out of compliance. AppZero also stresses that different versions of Windows are built on top of a shared kernel that evolves very slowly. With the end of support of Windows XP, and soon
Windows 2003, there is reason to believe that the number of critical vulnerabilities will increase.
