With the release of the SMS Inventory Tool for Dell Update and the upcoming SMS Inventory Tool for Microsoft Updates, SMS introduces a new set of PatchStatus and PatchState classes known as the Extended classes. These are denoted by the “Ex” suffix. Microsoft plans to use these classes extensively for future scan tools, so it will be good to get up to speed on their structure and the kinds of data available for reporting. My colleague, Eric Holz, has a short article that addresses this. You can check that out here.
