FontReg

FontRegis a lightweight command-line tool that can be used to repair the font registry as well as to install new fonts. Although it doesn't come wrapped in a graphical interface, the app turns out to be really easy to use, even by those without previous experience in console-based programs.

There is no installation involved, so you can unzip the downloaded file and use FontReg right away. Plus, you can keep the utility stored in your collection of portable software and launch it on any computer to fix or install new fonts, without any prior setup.

Administrative rights are necessary to get the tool up and running properly. If you call FontRegis' process without any arguments, it attempts to repair the font registry, without any intervention required on your behalf.

To install a new font, you first have to make sure that its files are saved in the same directory as FontRegis. The program offers support for FON, TTF, TTC and OTF filetypes. Then, you can use the /copy or /move switch. Besides copying or moving the fonts to the C:\Windows\Fonts path, the application is also responsible with registering them, to make sure you can start using the new fonts right away.

The software utility looks for any unused font registrations and removes them in order to free up space and declutter the hard drive. When it comes to repairing the fonts, the program takes all filetypes into account, except for FON because it's not possible to find out which fonts have hidden registrations.

The goal of FontRegis is to replace the old fontreg.exe that came pre-installed with Windows. It doesn't print any messages during runtime because it's completely silent (some users might think that the application doesn't work, instead). Although it hasn't received updates for a long time, our tests reveal that FontRegis still works with newer OS implementations, including Windows 10.
