When you reach the end of your PowerPoint in presentation mode, the last thing you see isn’t your final slide, but instead, a black screen with the text “End of slide show, click to exit.” It’s there to show the presentation has finished, but if you’ve already designed a slide for that, the black screen is redundant.
The final black slide is enabled by default, but you can turn it off for all presentations.
Go to File > Options and click Advanced on the left. Scroll down to the Slide Show section and untick End with black slide.
Click OK to save your changes.
