EdgeHTML
EdgeHTML is a proprietary layout engine developed by Microsoft for the Microsoft Edge web browser. It is a fork of Trident that has removed all legacy code of older versions of Internet Explorer and rewritten the majority of its source code with web standards and interoperability with other modern browsers in mind. The rendering engine was first released as an experimental option in Internet Explorer 11 as part of the Windows 10 Technical Preview build 9879.
Usage in Windows
EdgeHTML is designed as a software component to allow software developers to easily add web browsing functionality to their own applications. It presents a COM interface for accessing and editing web pages in any COM-supported environment, like C++ and .NET. For instance, a web browser control can be added to a C++ program and EdgeHTML can then be used to access the page currently displayed in the web browser and retrieve element values. Events from the web browser control can also be captured. It's also used to render WinRT-apps that are based on web technologies.
