Microsoft Edge allowed you to read your favorite eBooks directly in the browser. Microsoft made it possible to open EPUB files via Windows 10 Creators Update, which brought a number of features including support for the EPUB file format. 


Adding EPUB support to Edge was a strategic decision because Microsoft sold eBooks in the Microsoft Store app. In July 2022, once Microsoft removed eBooks completely, it also discontinued support for EPUB files, which means it is no longer possible to open eBooks with the .epub extension with Microsoft Edge.



Fortunately, you can open EPUB files on Windows using an application that supports them, convert EPUB files to other supported file formats, and then read them on your PC.
