Microsoft wants businesses to provide their own list of websites that will be automatically loaded in Enterprise Mode. Websites can’t ask to be rendered in this mode, and it won’t appear in the normal menus as an option for typical users. Rather than stick with Internet Explorer 8 on Windows XP, which is reaching the end of its long life, Microsoft wants to encourage these businesses to upgrade to a modern version of Windows and Internet Explorer. Some businesses have standardized on older versions of Internet Explorer and may use internal web applications that just don’t function with modern versions of Internet Explorer. A website that loads in Enterprise Mode renders like it did in Internet Explore 8. Internet Explorer’s Enterprise Mode is a special compatibility mode in Internet Explorer 11.
