The Microsoft Patch Qualification team strategically tests the latest Rockwell Software product release and two prior, as we cannot test every possible OS combination.
We take into consideration Microsoft's product support lifecycle strategy and the software requirements of each Rockwell Software package. We feel our selection process provides the best testing coverage over supported combinations.
Please note that if you see a critical patch qualified on a different OS/CPR combination, we would suggest that the same patch on an alternate OS/CPR combination, should be considered as relatively 'low risk' and could be applied at your discretion.
As always, we do suggest that before implementing any Microsoft updates, you should verify them on a non-production system, or when the facility is non-active, to ensure that there are no unexpected results or side effects.
