There's been quite a delay for Windows XP Service Pack 2, with good reason: overwhelming security holes found within the Windows operating system. Turn your head for only a few moments, and another patch is released under the "Critical" heading in of Microsoft's Windows XP Update tool. It gives us great concern that despite the money we've spent so many cumulating holes open us up to the world of the unknown.Microsoft Windows is the most widely used operating system in the world. Which brings me to this thought: An operating system so popular, has the most security holes--will be probed and picked at more than any other. Its popularity has opened doors not just for common users, but for hackers at large.
