To set a default theme in PowerPoint, you need to create and save a default theme template. Here are the steps to do this:
- Open PowerPoint and start a new presentation.
- Go to the Design tab and choose a theme that you want to set as the default.
- Customize the theme as needed (fonts, colors, effects).
- Once you have your desired theme, go to File > Save As.
- In the file type dropdown, select PowerPoint Template (*.potx). This will change the folder location to Custom Office Templates.
- Click on More options to open the file dialog box. Replace the file path with *%Appdata%\Microsoft\Templates* and press Enter.
- In the Templates folder, navigate to the Document Themes folder. If a file named Default Theme.potx exists, you can back it up by copying it.
- Save your customized theme as Default Theme.potx in this folder. If prompted, choose to overwrite the existing file.
- Close PowerPoint and then open it again. Your default template will now be available as an option when you create a new presentation.
If you are not seeing the option to set a theme as default by ctrl+clicking, this method will allow you to set a default theme manually.
