It may be that you changed some font styles on your slides before you changed the font styles on the slide master. Microsoft PowerPoint always preserves changes you make to specific slides. To make those slides follow the current master styles:
- Display the slide in normal view. On the Format menu, click Slide Layout.
- Point to the type of layout the slide uses, right-click the slide layout thumbnail, and click Reapply Layout.
I want to replace all of one type of font with another font.
When you want to replace every instance of one font with another, use the Replace Fonts command.
- On the Format menu, click Replace Fonts.
- In the Replace box, click the font style you want to replace.
- In the With box, click the font you want to use as the replacement, and then click Replace.
- Repeat steps 2 and 3 for all the font types you want to change in the presentation.
Some font styles are missing from my presentation.
When you show a presentation on a different computer than the one you used to create it, some TrueType fonts may not be available. To prevent this situation, you can embed some TrueType fonts when you create the presentation. (Some fonts have license restrictions and you can't embed them.)
- On the File menu, click Save As.
- On the toolbar, click Tools, click Save Options, select the Embed TrueType Fonts check box, and then do one of the following:
- To embed only those characters used in the presentation, select Embed characters in use only (best for reducing file size).
- To embed all the characters in the font set, select Embed all characters (best for editing by others).
