In the last two days, Microsoft released two builds for Windows 10 consecutively. They were build 10158 and 10159. In build 10158, Microsoft focuses on adding many high-demand features to the new web browser Microsoft Edge. Multiple homepages is one of them.
With this feature enabled, Edge is able to open a set of webpages whenever you launch it. To do this, open Microsoft Edge and hit the ellipsis icon on the top right corner. Then select Settings.
In Settings pane, you’ll see the section “Open with.” To make Edge open multiple pages when launch, you need to select “A specific page or pages.” Then choose “Custom” in the drop-down menu. Now you can enter any web address to like into the box.
And that’s all. One the other hand, if you like to set a page when open a new tab, you can learn how to do it here. Enjoy!
