I would also recommend downloading a program called font frenzy this will clean up your fonts and delete or repair broken ones. You can access the activated fonts in the Active fonts panel inside Creative Cloud desktop app and in the font list in your desktop apps. The fonts are now installed and will appear in the font menus of your applications. otf fonts are single-file fonts, and do not include font suitcases. Often a family of outline fonts will be associated with a single font suitcase. Using this method the fonts are installed into a none essential system folder and is made available to all programs that uses fonts as it is referenced in your font installations and will only load the font as you need it. Then select the toggle to activate (or deactivate) a font family, individual font weights, or styles. For PostScript Type 1 fonts, this includes both the outline font files (red A icons) and the font suitcases. Check it for yes this makes your system run so much faster especially withinn programs like photoshop that initialises the type tool on every use, If you have thousands of fonts this will be slow.
Then when you go to install a font you will see a new option at the top asking if you would like to install this font as a link. Then go to c:> Windows > Fonts and select font settings on the left hand side and check the allow fonts to be installed as shortcuts box. Hundreds of fonts installed can cause major hangups on your computer I reccommend never installing fonts into your windows directory instead create a folder somewhere not within the system section ie my documents download all your fonts to there.
