Add a New Font to Your Computer
For Windows XP:
1) Start Botton > Settings > Control Panel
Installing fonts on Windows Vista and Win7 is probably very similar.
To select more than one font to add, press and hold down the CTRL key, and then click the fonts you want.
For TrueType, Raster, or Adobe Type 1 fonts, you can also add the font by dragging the appropriate files to the Fonts folder. If you want to see the file extensions in Windows Explorer, click View, click Options, and then click the View tab. Clear the Hide File Extensions For Known File Types check box.
