To install a font on Windows, you can follow these steps:

1. After downloading the zip file, click on "Extract all files" or drag and drop the files elsewhere from the zip window.

2. Install the font: Right-click on the font file and select "Install" from the context menu. Alternatively, you can double-click on the font file, and a preview window will open with an "Install" button. Clicking on "Install" will initiate the font installation process.

3. Font installation complete: After the font is installed, you can start using it in various applications that support fonts, such as word processors or graphic design software. The font will also be available in your system's font list for selection.

Note: In some cases, you may need to restart applications, like word processors, for them to recognize and display the newly installed font.

By following these steps, you should be able to install a font on your Windows system successfully.
