The software update plug-in manages all of the Patch Management Solution for Windows functionality on a client computer. When the system assessment scan tool reports to Notification Server that a certain software update is required for a managed computer, the update is then sent to the software update plug-in. The software update plug-in ensures that the update is applicable and not already installed, and then installs it.
After you install the software update plug-in on a managed computer, the Software Updates tab appears in the Symantec Management Agent user interface. This tab displays the status software updates for that computer. To open the Symantec Management Agent user interface, click the Symantec Management Agent icon in the system tray of the managed computer.
