Support will end on July 11, the next date for Microsoft’s monthly security patches and software updates.Security updates will also end, according to a posting on the Microsoft Security Response Center. Microsoft said it wasn’t feasible to make extensive changes to eliminate a security vulnerability since the underlying architecture of Windows Explorer for older versions of Windows is much less robust, wrote Christopher Budd, a program manager with Microsoft’s security response center. “Due to these fundamental differences, these changes would require re-engineering a significant amount of a critical core component of the operating system,” Budd said. As a result, applications may not run on the updated system, he said.Microsoft advised those still using the operating systems put them behind a perimeter firewall that filters traffic on TCP port 139, which will block attempts to exploit the problem, Budd said. Further, support for Windows XP Service Pack 1 will end on Oct. 10. — Jeremy Kirk, IDG News Service (London Bureau)Related Links: Microsoft’s Windows Vista Beta (Not) Publicly Available Microsoft Unveils New Security Services A Win for Microsoft in Massachusetts?This article is posted on our Microsoft Informer page.
