Question

what are the different ways in which you can start creating a presentation

Answer 1

When PowerPoint 2007 is opened, a blank Title slide appears by default as the first slide in your new presentation. You can start a new presentation when you first open PowerPoint or after PowerPoint is already open. To change the layout of an open slide, click on the Layout button in the Home tab.
