Microsoft PowerPoint Presentation

Microsoft PowerPoint is a presentation tool included with Microsoft Office. PowerPoint allows you to make interactive multimedia slideshows to present information. When you open a PowerPoint Presentation (.ppt, .pptx), the PowerPoint software is launched, but the presentation doesn't start automatically. If you want the presentation to start immediately in full screen mode and provide a more polished and professional experience, you should save it as a PowerPoint Show.
