==Introduction==
Microsoft Edge, initially developed under the codename Project Spartan, is a web browser in development by Microsoft. Officially unveiled on January 21, 2015, and first publicly released as a preview on March 30, 2015, it will replace Internet Explorer as the default browser on Windows 10 PCs, smartphones and tablets.

Microsoft Edge is designed to be a lightweight web browser with a layout engine built around web standards, removing support for legacy technologies such as ActiveX in favor of extensions and integration with other Microsoft services, such as the digital assistant Cortana, OneDrive, and also includes annotation tools and a reading mode.
