Configuring Enterprise Mode in Windows 10

In Windows 10, Internet Explorer 11 behaves the same as Internet Explorer 11 on Windows 7 or Windows 8.1, using the Trident engine. This should help ease some Windows 10 migrations and reduce or eliminate compatibility issues for customers who already upgraded to Internet Explorer 11. In enterprise deployments, Microsoft recommends Internet Explorer 11 as a stable, reliable web platform for complex line-of-business (LOB) apps designed to run in a web browser.

By comparison, Microsoft Edge renders all webpages using the new EdgeHTML engine, using a modern standards mode. You can switch to Internet Explorer 11 for sites that are on your intranet as well as those included on a managed list of sites or on a Microsoft-managed Compatibility View list of public websites. Microsoft Edge also can identify sites with legacy technology, such as ActiveX controls, and offer to manually switch to Internet Explorer 11 for backward compatibility.
For external and internal sites that require a different document mode to render properly, particularly sites designed for older versions of Internet Explorer, you can enable Enterprise Mode and then create a list of sites with custom settings for each one. Once the sites are configured, there’s nothing that end users need to know or do; Internet Explorer will switch modes as needed to render the site or web app in the correct mode.

Enterprise Mode is available for all editions of Internet Explorer 11 but is turned off by default. You won’t be able to use Enterprise Mode unless you turn it on by enabling a Group Policy Object or setting a registry key.

Enterprise Mode works by checking addresses against a list of websites. When a site matches an address on this list, Internet Explorer 11 uses the specified mode. On Windows 10, Microsoft Edge switches to Internet Explorer 11 automatically for sites on the Enterprise Mode Site List.

To enable Enterprise Mode, you need to change a Group Policy setting. This can be accomplished using domain settings or, for a single Windows 10 device, you can use the Local Group Policy Editor (Gpedit.msc). Navigate to Computer Configuration > Administrative Templates > Windows Components > Internet Explorer, and then enable the Use The Enterprise Mode IE Website List policy.

You can also enable Enterprise Mode using the Registry Editor (Regedit.exe). To enable Enterprise Mode for the currently signed-in user account only, edit the SiteList value (type REG_SZ) in HKCU\Software\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode. (You might have to create that key and its associated value if they don’t already exist.)

To turn on Enterprise Mode for all users on the PC, edit the SiteList value (type REG_SZ) in HKLM\Software\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode. (Note that this value uses the HKLM node rather than HKCU.)

Simply enabling this setting isn’t enough. You also have to specify where the Enterprise Mode site list is stored. To enter the location of your Enterprise Mode site list in Local Group Policy Editor or in Regedit, use the appropriate syntax (substituting the correct server, user, and page names, as needed):

■ HTTP location: http://localhost:8080/sites.xml

■ Local network: \\network\share\sites.xml

■ Local file: file:///c:\\Users\\\\Documents\\testList.xml
