Font Frenzy cleans out unnecessary Windows XP fonts
It turns out Windows XP installs just 44 fonts. All the other fonts on your system were probably installed by other programs. And you can safely remove the majority of them. But who has the time to sift through all of those fonts one by one?
Font Frenzy simplifies things by letting you uninstall any non-Windows font with just a few clicks. Worried that you might accidentally delete fonts that you meant to keep? No problem, you can create a snapshot of your font directory which you can use as a restore point. You can reinstall all of your fonts or just pick and choose from your backup directory.
There's also a handy font viewer for seeing how various fonts look at different point-sizes, and a browser for adding and removing fonts on a case by case basis.
Keep in mind that this software is designed for Windows XP. There are several new fonts included in Windows Vista. So using Font Frenzy to remove all non-system fonts in Windows Vista could actually result in removing necessary fonts.
