Windows 7 comes with TrueType fonts and OpenType fonts. They work with a variety of computers, printers, and programs.
TrueType fonts (.ttf/.ttc) can be scaled to any size and are clear and readable in all sizes. They can be sent to any printer or other output device supported by Windows.
OpenType fonts (.otf) are related to TrueType fonts, but typically incorporate a greater extension of the basic character set, such as small capitalization, old-style numerals, and more detailed shapes, such as glyph and ligatures. OpenType fonts are also clear and readable in all sizes and can be sent to any printer or other output device supported by Windows.
PostScript fonts are fonts created by Adobe Systems that are smooth, detailed, and of high quality. They are often used for printing, especially professional-quality printing, such as books or magazines.
Tip
If you need a default Windows 7 font, then please just post a request for it here, and I'll be happy to post a clean copy of it for you.
Warning
If you install a TrueType font with exactly the same name as a PostScript font on the same computer, Windows won't know which one to access, which could result in a font type being altered. To avoid this, don't install different types of fonts with the same name.
Here's How:
1. Download the font that you want to install. NOTE:You can download fonts from a software program, the Internet, or your organization's network. You can get free fonts from the links at Microsoft Typography - Font foundries. WARNING:Before you download a font, make sure you trust the source.
2. Right click on the font, click on Properties, click on the General tab, click on the Unblock button if there, and click on OK. (See screenshot below) NOTE:If there is not a Unblock button there, then the font has not been blocked. Continue to step 4.

Was looking at your reply from my laptop which i installed Windows 7 and saw that I had more fonts displaying on my laptop than on my desktop pc - which only shows 9 fonts installed. But when you click and drag new fonts on my desktop setup is says that its already there and do you want to replace it. But it never shows. Looks like something has gone weird with my Windows 7 install and most of the default fonts are not displaying CRAP!
Seems I have the same prob. in x64. Checked in x86 and all is well. Thought it might be caused by font nav. which I've used to keep track of fonts for years. It's not installed on 7 x86.
