You can update your ZENworks 11 SP2 software on all devices in the Management Zone where the software is installed. Update downloads can be scheduled. Software updates are provided at the Support Pack release level and you can choose whether to apply each update after viewing its content (Support Pack releases are cumulative). You can also download the latest Product Recognition Update (PRU) to update your knowledgebase so that ZENworks Inventory can recognize newer software.
