A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
As Steve has pointed out, PowerPoint does not have an equivalent to Normal.dotm. But you can give it one using the following steps:
- Create a template with your preferred default fonts.
- Save it as Default Theme.potx.
- Close PowerPoint.
- Open a File Explorer window.
- Paste the text below into the address bar:
%appdata%\Microsoft\Templates\Document Themes - Drag Default Theme.potx into the Document Themes folder.
- Open PowerPoint, then press the Ctrl + N keyboard shortcut. A new presentation is created using your default fonts.
To create a new file, you can also use File>New and choose the Default Theme icon, which will be at the left end of the top row of templates/themes.

**Note:**Any changes you make in Slide Master view affect all the slides that use the master.
