There may be times when you do not want all your slides to appear in a slide show. If a slide is incomplete, or not relevant to the audience whom you are presenting to, you can prevent the slide from being displayed in the presentation without having to delete it from the file.
Hiding a slide is very simple to do. Open your PowerPoint presentation and select the side that you do not want displayed during your slide show. From the Slide Show menu, click the Hide Slide option. Repeat this step for any additional slides that you want to hide.
