Open the Fonts window in Windows XP and Vista and you'll see the font names, probably with icons to tell you whether they're TrueType or OpenType, but that's about it. Windows 7 sees some useful font-related improvements.
Open the new fonts window and you'll find a little preview for every font, giving you a quick idea of how they're going to look.
The tedium of scrolling through multiple entries for each family, like Times New Roman, Times New Roman Bold, Times New Roman Bold Italic and so on, has finally ended. There's now just a single entry for each font (though you can still see all other members of the family).
And there's a new OpenType font, Gabriola, added to the mix. It's an attractive script font, well worth a try the next time you need a stylish document that stands out from the crowd.
