If your fonts aren't appearing properly in your programs' font lists, or if fonts look garbled in your documents, you may need to rebuild your font cache. The font cache is a file or set of files used by your computer's operating system to manage and display the fonts that are installed on your computer. The font cache may become corrupted for a variety of reasons, including disk errors and viruses. You can repair a corrupted font cache by deleting it, causing the operating system to rebuild it on the next restart.
