Microsoft will be releasing up to 7 updates with 3 marked as critical and 3 marked as important. An additional patch is marked 'moderate'.The three patches that are “Critical” all involve vulnerabilities that could create a remote code execution situation, which means that a hacker could gain control over the PC. All of the major 32-bit and 64-bit versions of Windows Vista/XP/200 are affected and at least four of the patches we know for certain will require a reboot once they are installed. It should come as no surprise that most of the patches this time around focus on Internet Explorer versions 6 and 7.
