In Windows 11, Internet Explorer has been removed. Thus, it is no longer possible to launch Internet Explorer in Windows 11.
Therefore, Microsoft has introduced compatibility mode or Internet Explorer mode in their latest browser, Edge, to make the websites backward compatible.
By using this compatibility mode, one can continue to use the old websites in the Microsoft Edge browser. This means that there is no need to download a third-party browser to resolve compatibility issues. This will help organizations tremendously, as they will not have to redesign their web page to make it compatible with the Edge browser.
