Note: If you created templates, they may be under the Personal tab. Business customers may see a Company tab with themed templates.
If you've created a template or gotten one from elsewhere, store it in the right location to make it easy to apply:
C:\Users\\AppData\Roaming\Microsoft\Templates
Replace with whatever your user name is on this computer.
What is a PowerPoint template?
A PowerPoint template is a pattern or blueprint of a slide or group of slides that you save as a .potx file. Templates can contain layouts, colors, fonts, effects, background styles, and even content.
You can create your own custom templates and store them, reuse them, and share them with others. You can also find hundreds of different types of free templates on Microsoft Create and on other partner websites that you can apply to your presentation.
