Microsoft on Tuesday released 84 patches affecting 15 product families – including a few you’ve possibly never encountered. Eight of the addressed issues are considered by Microsoft to be of Critical severity, though none of those affect Windows, nor are they expected to be exploited within the next 30 days.
