How to Enable the IE Mode in Microsoft Edge on Windows 10 and 11

In IE Mode, Edge users will see websites as if they were opened in Internet Explorer 11 (Trident MSHTML engine is used for rendering). This means that a user doesn’t need to install an additional browser on their computer to view legacy websites. In this mode, Edge replaces its user agent and presents itself as IE 11. ActiveX, COM, Java, Internet, and all the other components that have been developed for IE are available. 

In order to configure the Internet Explorer compatibility mode in Microsoft Edge on Windows 11:

1. Start the Microsoft Edge;
2. Open the browser settings;
3. Go to the Default browser section (edge://settings/defaultBrowser);
4. Change Allow sites to be reloaded in Internet Explorer mode (IE Mode) to Allow and restart your Edge browser; 
5. Now you can view any website in IE compatibility mode. To do it, right-click the tab and select Reload tab in Internet Explorer mode option from the menu;
6. The IE icon appears next to the website name in the navigation bar. If you click it, you will see the message: This page is open in Internet Explorer Mode. 

You can create a list of websites that you always want to open in IE mode. Add their URL addresses in edge://settings/defaultBrowser -> Internet Explorer Mode Pages -> Add.
