Maybe you're trying to make a snazzy invitation or cover page for something. You look at all the fonts you have in MS Word, and you're just not satisfied. Nothing looks cool enough. Well, all you have to do is download new fonts (most are available for free on the internet) and install them. Sure, you say, that's easy if you're geeky. No, it's easy even if you're not.
1. Go to a legitimate website, like http://www.1001freefonts.com. (click on the different letter icons there to browse. FYI, the PC Fonts, Mac Fonts links up top are just ads)
2. Download the font you want to anywhere on your computer. You might want to just create a folder first on your desktop (to keep it simple). Right click on your windows desktop, click on New > Folder and name the folder "Downloaded Fonts". Then download your fonts there.
3. The fonts are usually in a zip file (meaning, it's been compressed to save size or to combine some files together). Just right-click, and choose "Extract All Files" and keep clicking 'continue' until it's down extracting or 'unzipping'. You should see the files.
4. Right-click on the font file (probably ending in TTF or FON) and click copy.
5. Open up your Windows Explorer, and navigate to the following: C:\WINDOWS\Fonts (you can even just copy and paste that in the address portion of your explorer window)
6. Right click, and paste. You're done! When you open Word or Excel or any app using fonts, you should see the new font in the fonts list.
Please note that if you are emailing your doc to anyone, your new doc won't show with the new font on their computer, unless the person you emailed it to has installed the same font. But they can still read your doc of course, the font will be replaced with a generic font.
EXTRA TIP: If you are frequently experimenting with new fonts, you may want to just create a new shortcut on your windows desktop (right-click, New > Shortcut) and type in the C:\WINDOWS\Fonts path. That way, you have quick access to your fonts folder.
