When the Software Updates Client Agent in Microsoft System Center Configuration Manager 2007 is enabled, it sends a policy to the client computers that are assigned to the site. This policy requests that the software updates components be enabled. These components work together to perform compliance assessment scans and install software updates at their configured deadline, prior to deadline according to a user-specified schedule, or when they are manually initiated. These components also reevaluate whether previously installed software updates are still installed, and if they are not still installed, then install them again. The Software Updates Client Agent properties are site-wide client settings.
