Microsoft Edge

Microsoft Edge is a web browser designed by Microsoft. It came out as "Project Spartan" in Windows 10 build 10009 and it stayed in with the RTM in 2015. Microsoft Edge was made to replace Internet Explorer.

It is the default browser in Windows 10, Windows 10 Mobile and Windows 11.

Differences from Internet Explorer

 * Microsoft Edge used the EdgeHTML engine to render pages once and now it uses the Chromium engine rather than IE's Trident engine.
 * The EdgeHTML variant was only available for Windows 10. However, the Chromium variant added support for macOS, Linux, Android, as well as Windows 7 and 8.x. Due to restrictions in the terms of the App Store, Edge on iOS is based on WebKit.

EdgeHTML and Chakra
It is based on the "EdgeHTML" rendering engine and the Chakra JavaScript Engine, now referred to as Microsoft Edge Legacy.

Transition to the Chromium engine
On 6 December 2018, Microsoft announced a plan to rebuild Edge from scratch as a classic Win32 application, which would be based on Chromium and would be available for Windows 10, Windows 8.1 and Windows 7. It is also planned to bring Edge to "other platforms like macOS". On or before 24 March 2019, preview versions of the Chromium-based browser were leaked to the internet. On or before 8 April 2019, preview versions of the new browser were officially released. The Chromium version of Edge was released on 15 January 2020 (codenamed: Anaheim).

On 17 August 2020, Microsoft announced that the legacy version of Edge would no longer be supported from 9 March 2021 and that they recommend people to switch to the Chromium based version.

Windows 10 build 19041.330 is the first build of Windows 10 to include Microsoft Edge Chromium.

Internet Explorer Mode
Microsoft Edge includes the Internet Explorer Mode, which uses the Trident engine of Internet Explorer 11 to display websites. Edge can be configured to display selected websites in Internet Explorer Mode, if they have trouble with the Blink engine. It is only available for Windows, intended for enterprise usage and to replace the Internet Explorer 11 app on Windows.
