How to enable Internet Explorer Compatibility Mode in Microsoft Edge

Microsoft Edge has an Internet Explorer mode for compatibility that can be used by organizations or older sites on the Internet. This module will allow users to access information on websites and services that use legacy technologies.

Microsoft made the decision to retire the old browser 26 years after it was launched in 1995. Now, instead of Internet Explorer (IE), the Edge browser is used in Windows 11, Windows 10, Windows 8.1, Windows 8, Windows 7 operating systems.

Many users have noticed that the Internet Explorer 11 browser has disappeared from Windows components. Even where there is Internet Explorer, after clicking on the shortcut of this browser, the Microsoft Edge browser running on the Chromium engine is launched.

Microsoft explains this by saying that Internet Explorer has become an outdated and less secure Internet browser, and the new browser uses modern technologies with a large number of diverse features.

This solution causes some problems, in particular with the display of outdated web pages on the Internet. Therefore, users can use the Microsoft Edge browser in Internet Explorer mode to view older websites.
