## Interoperability goals and enterprise guidance
|
|
|
|
Our primary goal is that your websites work in Microsoft Edge. To that end, we've made Microsoft Edge the default browser.
|
|
|
|
You must continue using IE11 if web apps use any of the following:
|
|
|
|
* ActiveX controls
|
|
|
|
* x-ua-compatible headers
|
|
|
|
* <meta> tags
|
|
|
|
* Enterprise mode or compatibility view to addressing compatibility issues
|
|
|
|
* legacy document modes
|
|
|
|
If you have uninstalled IE11, you can download it from the Microsoft Store or the [Internet Explorer 11 download page](https://go.microsoft.com/fwlink/p/?linkid=290956). Alternatively, you can use Enterprise Mode with Microsoft Edge to transition only the sites that need these technologies to load in IE11.

>[!TIP]
|
|
>If you want to use Group Policy to set Internet Explorer as your default browser, you can find the info here, [Set the default browser using Group Policy](https://go.microsoft.com/fwlink/p/?LinkId=620714).

|Technology |Why it existed |Why we don't need it anymore |
|
|
|---------|---------|---------|
|
|
|ActiveX |ActiveX is a binary extension model introduced in 1996 which allowed developers to embed native Windows technologies (COM/OLE) in web pages. These controls can be downloaded and installed from a site and were subsequently loaded in-process and rendered in Internet Explorer. | |
|
|
|Browser Helper Objects (BHO) |BHOs are a binary extension model introduced in 1997 which enabled developers to write COM objects that were loaded in-process with the browser and could perform actions on available windows and modules. A common use was to build toolbars that installed into Internet Explorer. | |
|
|
|Document modes | Starting with IE8, Internet Explorer introduced a new “document mode” with every release. These document modes could be requested via the x-ua-compatible header to put the browser into a mode which emulates legacy versions. |Similar to other modern browsers, Microsoft Edge has a single “living” document mode. To minimize the compatibility burden, we test features behind switches in about:flags until stable and ready to be turned on by default. |
