Remove Final Black Slide
By default, PowerPoint inserts a black screen at the end of every presentation that displays the text “End of Slide Show, Click to Exit.” This is by no means an attractive slide, but serves as a nice stopping point between the end of the presentation and quitting the slideshow completely.
To remove this, go to Tools > Options. Within the “View” tab, uncheck “End with black slide.” Simple enough. This technique also provides the opportunity to create your own proper ending slide.
Creating Your Own Final Slide
Since the end of linear presentations often conclude with a Question and Answer session, I find it convenient to create a special slide for this purpose, which remains as a backdrop while the speaker fields inquiries. I consider this a “graphic summary” slide. It includes the same background as the rest of the presentation to maintain consistency, as well as any logos, slogans, URL’s or other branding elements that reinforce the messaging. Since the wrap-up sessions can often drag on, it’s nice to give the audience something to look at—and even nicer when it’s a giant projection of your logo and URL.
