With this December Microsoft Patch Tuesday update, we see a relatively large set of updates. In total there are 13 Microsoft Security Updates; 3 with the rating of Critical and 10 with the rating of Important. This is a relatively large update from Microsoft and the potential impact for the updates is likely to be moderate.
As part of the Patch Tuesday Security Update analysis performed by the ChangeBASE team, we have seen moderate cause for potential compatibility issues.
Given the nature of the changes and updates included in each of these patches, most systems will require a reboot to successfully implement any and all of the patches and updates released in this December Patch Tuesday release cycle.
