Comparing with many EPUB readers, the classic Edge is fast with beautiful UI and it can render the EPUB page based on the CSS defined in the file rather than common styles. How to install the classic Edge? Here is the tip: First, you need Windows 10 LTSC 2019. This edition of Windows is designed for enterprise and only receives security updates. That means the version number is fixed but you are still covered with security updates. Windows 10 LTSC doesn't preinstalled with Edge browser so that we can install the specific versions of Edge we want. The Edge browser which contains EPUB reading function is in the 1809 version, the first release version not the updated version.
