"If it does, attackers will attempt to develop exploit code that can take advantage of those vulnerabilities on Windows XP. Since a security update will never become available for Windows XP to address these vulnerabilities, Windows XP will essentially have a 'zero day' vulnerability forever."
He points out that from July 2012 through July 2013, Windows XP received 45 patches, 30 of which were relevant to Windows 7 and 8 as well, and there is considerable flaw cross-over found among the three operating systems. XP is also by far the most malware-infected operating systems, he points out.
That is the Plan. Microsoft directing hackers on how to find exploits for XP.
