Ooh don't install them to the windows folder. It just makes your system run slower. What I do is have a folder on my desktop with all my downloaded fonts and when I want to use one or more I open my AMP font viewer program scroll for the font then click install temporarily. Very handy program and real easy to understand. Best of all its free. LOL
Here is a link to the AMP font viewer -
