Automatically show your presentation
PowerPoint
2016
Instead of opening your PowerPoint presentation file and then clicking F5 or using other ways to start the
presentation, you can save your PowerPoint file in the PowerPoint Show format. Also, this format prevents
changes in the presentation.
To save the presentation in the PowerPoint Show format, on the File tab, click the Save As... and then choose PowerPoint Show (*.ppsx):
This allows you to save the file on your PC, and when you click on it, the presentation starts automatically. No opening up PowerPoint program first!
