Have you ever applied a new Slide Master to existing slides in PowerPoint – and then found that the old Slide Master just disappeared! Poof – how did that happen? The typical answer to that question is your existing Slide Master was not “preserved”, and since no slides used it anymore, PowerPoint just decided to clean it up altogether. So if you don’t want this to happen again, then you must preserve your Slide Masters.
