Sometimes Machines will get updates from WSUS and not report. This is usually caused by Duplicate WSUS SIDs shared between machines. This is usually a result of cloning or deploying from a template. Once you run this script the machine will delete its current SUS ID and reach out to the configured WSUS server to get a new one.  Please rate if this is useful.
