OK.. but be CAREFUL! If you go crazy and download a ton of fonts (like most of us do) and then just install them all in the Windows/Fonts folder... everything will be much slower. When you boot up.. the system will be slower because windoze needs to load all the fonts. When you kick of elements, boy will it slow down because adobe is reading and creating previews for EVERY font...

It is much better to only activate those fonts you need when you are working on a layout. I use a 3rd party font viewer (printer's apprentice) to preview, organize and activate/deactive my fonts as I need them. This is the approach anyone who has over 300 fonts should use.. unless you don't mind the wait while they are loaded!
