Microsoft Patch Tuesday : April 2013

Executive Summary

With this April Microsoft Patch Tuesday update, we see a set of 9 updates; 2 of which are marked as “Critical” and 7 rated as “Important”.
The Patch Tuesday Security Update analysis was performed by the Quest ChangeBASE Patch Impact team and identified a small percentage of applications from the thousands of applications included in testing for this release which showed amber issues.

Of the nine patches, 6 "require a restart to load correctly", 3 "may require a restart", so as usual, it is probably best to assume all require a restart to be installed correctly.
