Replace all the fonts in the Presentation at One time:

Is one of these scenarios familiar?
• You have started a new presentation and copied some slides from another presentation into it. However, the fonts of the combined presentation are different.
• You have a basic starter presentation but want to change all the fonts for this new version.
• You are reviewing a presentation for a colleague and would like him to change the fonts before the big day.
Answer:
PowerPoint has a convenient feature that allows you to make a global change to all the fonts in the presentation at one time.
1. PowerPoint 2007 - In the Editing section on the Home tab of the ribbon, click the Replace > Replace Fonts...
2. PowerPoint 2003 - Choose Format > Replace Fonts... from the menu.
3. In the Replace Font dialog box, under the heading Replace, select the font you wish to change from the drop down list of fonts in this presentation.
4. Under the heading With, select the new font for the presentation.
5. Click the Replace button. All the text in the entire presentation that used the original font is now replaced with your new choice.
6. Repeat the process if your presentation contains a second font that you wish to change.
