"I downloaded a font and I want to use it in Microsoft Word. The font is currently on my desktop, but it doesn't show up in the fonts list in Microsoft Word. How can I add this new font to Microsoft Word."
All Microsoft Office applications pull the available fonts list from the system fonts stored in the Windows directory. You need to install the font in the Windows Fonts folder in order to access the font from Word, PowerPoint, Excel or any of the other Microsoft Office applications.
