FontFrenzy 1.5

This is the software publisher's description. 

It's a fact that Windows fonts slow down your computer. Every font that gets installed on your PC slows down the boot-up time and slows down your normal operational speed.

Many programs that you install automatically add their own set of fonts, and very soon you can end up with a frenzy of unnecessary fonts clogging up your computer. Unless you use all of these fonts regularly, they are simply wasting your system resources.

Font Frenzy is a free font manager with some unique features not found in any free font program. Not only will it help you to view, install, and uninstall your fonts - it can help you "defrenzy" your whole font folder and put an end to font frustration and slow boot-up times.

Strip away all your excess fonts and restores your system to only the fonts that are essential to Windows, giving you the maximum performance speed possible.

Note that you'll need to register FontFrenzy after 40 days from installation (registration is free).
