Working with the Slide MasterThere are two masters for every presentation - a slide master and a title master. The slide master controls the formatting on all slides. If you apply a new design template, modify the color or size of slide titles, or change the background color on the slide master, all slides reflect the change. If you add a graphic to the slide master, it appears on every slide. Likewise, if you modify the layout of the title master, the slides you've designated as title slides also change.Edit the slide master of a presentation to change the font and add an image to the background:Load the Microsoft PowerPoint programClick on Open an Existing PresentationOpen the file on disk called www.pptTake a moment to scroll through the presentationOn the View menu, click Master.
