How to Enable or Disable Internet Explorer Edge Mode in Windows 10

   Information

In August 2013, Microsoft announced that document modes would be deprecated starting with Internet Explorer 11. Any websites that need one of the deprecated document modes to render correctly will have to be recoded to adhere to web standards going forward.

In Windows 10, Internet Explorer includes a new updated Trident rendering engine called Edge.

By default, if a website calls for compatibility mode, then the older and more resource intensive Trident engine from IE11 will display the site, otherwise, the more lightweight and updated IE12 Trident engine Edge will handle it instead.

A new flag in the browser allows users to control when Edge mode is used.

For more detailed information, see:

• Document modes are deprecated
• Living on the Edge – our next step in helping the web just work

• Internet Explorer 12: Big changes are coming to Trident - Neowin

This tutorial will show you how to set Internet Explorer Edge Mode to be automatic, enabled, or disabled for your user account in Windows 10.

   Note

If you disable Edge mode, then you will not be able to use "Edge" in F12 Developer Tools.
