If you create presentations as part of your job, your presentations will follow your company style guide and use your company colors, fonts, and logo. You can edit a PowerPoint design template every time you create a new presentation. But what if you need to be consistent every time? The answer is to create a new default design template. With your own template, your custom formatting is always front and center when you open PowerPoint.
