You can use the default Windows’ zip file extractor, by opening the zip file in a new tab and then moving the wordpress-seo folder on your Downloads folder, or use a program called WinRAR that permits to extract zip, rar and 7z files on your computer. To do the latter, here’s the link to download WinRAR. Select the language you want with the operating system architecture your computer has (to find it, search “Control Panel”, then go to “System & Security” and then on “System” and you can find the architecture your system has), then install it, and after integrating it with major archive types, right click on the zip file and click on “Extract Here”.
