Using the Slide Master vs. duplicating slides
Two quick ways of populating your slides with the same layout, headers, etc. are using the Slide Master and duplicating slides. PowerPoint always creates a master slide, when either a design template or color scheme is chosen.
A Slide Master will apply whatever elements you assign to the master slide to each and every slide, except for the first slide (if you choose to skip that one). Additionally, to change an element placed on the master slide, you only edit the master slide. The master slide can be very helpful when setting up multimedia, kiosk displays, or in adding in some elements to a presentation, such as the title to every slide.
A second means (and in some ways, easier) is to duplicate slides.
Duplicating slides is very easy to do.
