How can I copy the design from one PowerPoint presentation to another?

To copy the design from one PowerPoint presentation to another, simply open both presentations and go to the slide sorter view. Then, select the slides with the desired design, right-click, and choose “Copy.” Next, navigate to the other presentation, right-click on the slide where you want to paste the design, and select “Paste.” This will transfer the design elements, including the layout, colors, and fonts, to the new presentation.
