Improved web app and website compatibility. Through improved emulation, Enterprise Mode lets many legacy web apps run unmodified on Internet Explorer 11, supporting a number of site patterns that aren’t currently supported by existing document modes.
Tool-based management for website lists. Use the Enterprise Mode Site List Manager tool to add website domains and domain paths and to specify whether a site renders using Enterprise Mode. You can download the Enterprise Mode Site List Manager tool from the Internet Explorer Download Center.
Centralized control. You can specify the websites or web apps to interpret using Enterprise Mode, through an XML file on a website or stored locally. Domains and paths within those domains can be treated differently, allowing granular control. Use Group Policy to let users turn Enterprise Mode on or off from the Tools menu and to decide whether the Enterprise browser profile appears on the Emulation tab of the F12 developer tools.
