PowerPoint templates are designed to engage your audience visually and save you time. When you start creating a new presentation file, always make sure you use a template.
Pros of using a template are:
❌ Figure: Bad example - Not using the corporate template (in this case not SSW)
✅ Figure: Good example - That's a mighty fine looking template you got there
How to pick the template: In newer versions of PowerPoint, it is necessary to add your custom template to: C:\Users<UserName>\Documents\Custom Office Templates\
They will then appear in the PowerPoint list when creating a new presentation. You can also find a more in-depth guide on how to create PowerPoint templates and how to use a personal template.
✅ Figure: Good example - Your custom template appears in PowerPoint
