The Enterprise mode introduced by ie11 is summarized, and some references are directly referenced in English. Note that some references are annotated in Chinese. For your reference.

1. The purpose of introducing enterprise mode in ie11

(1) Starting with Windows 8.1 update, enterprise mode is added to ie11.

Enterprise mode is turned on by IT managers using group policy settings for specific domains or pages. it's much like the Compatibility View settings, but provides Internet Explorer 8 compatibility. webpages that work in Internet Explorer 8 work seamlessly in enterprise mode.

Ie11 displays the enterprise mode icon next to the address bar when displaying a page in enterprise mode.

To turn off enterprise mode on a webpage, change the emulation tool's profile drop-down to the desktop option or toggle the enterprise mode option in the Tools menu.

When this option is selected, ie11 behaves like Windows Internet Explorer 8.

Ie11 in enterprise mode presents an Internet Explorer 8 User-Agent string to servers by default. [1]

(2) Enterprise mode is basically IE8 compatibility mode on an enterprise level, when it's enabled for a specific site, this site will be displayed in compatibility mode for ie8. this is meant to move the move to Windows 8.1 for enterprise Windows 7 MERs. generation of their internal company sites were designed for IE8 or lower, upgrading windows wowould also mean upgrading to ie11 so these sites wowould need some upgrading too. system admins who are upgrading their company to ie11 can provide IE with a list of sites they 'd like to be displayed in enterprise mode, or employees can manually turn on Enterprise mode via the Tools menu if they sense a site isn' t working like it shoshould. [2]

(3) IE8 is the browser variant that Microsoft integrated into Windows 7, which is the newer version of Windows favored by venture business users. similar to the case with Windows XP, when businesses have built and certified line-of-business apps specifically for the Windows 7/IE8 combination.

Microsoft has rolled out subsequent ie releases (ie9, 10 and most recently, 11) that can run on Windows 7. but not every enterprise is willing or able to move to these newer ie variants, in part because their companies have standardized on Windows 7/ie8.

This situation becomes especially problematic for Microsoft and its customers as Microsoft rolls out new software and services that no longer support the older ie variants. for example, office 2013 and Office 365 don't support ie8. if a company is stuck on IE8, its admins might understandbly be reticent to move to Office 365 if IE8 isn't supported.

There may be a Microsoft-made solution to this dilemma, however. Sources say it's a new ie feature known as emie.

Users who need IE8 to view certain Intranet sites and internal apps wowould still be able to move to ie11 on Windows 7 (or Windows 8.x) thanks to the new compatibility mode functionality. but they still wocould be able to make use of all the rest of ie11's features the rest of their browser needs. [3]

2. How to configure enterprise mode.

Enterprise mode can be enabled locally or via group policy.

Group Policy allows it admin to be configured so that employees of the company can use internal Web Services in enterprise mode. A single user can also set the Group Policy or registry to enable the enterprise mode of the local machine to take effect. The following describes how to configure the local enterprise mode (only the Registry configuration methods are listed. For more information about how to set the Group Policy, see references ).

2.1 set enable [4]

(1) Open the Registry Editor-regedit.exe and goHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode.

Note:If you do not have these keys, you can create them by yourself.

(2) In the right pane, right-click and clickNew, ClickString Value, And then name the new valueEnable.

(3) Right-clickEnableKey, clickModify, And then typeValue DataTo point to a server that you can listen to for updates.

YourValue DataLocation can be any of the following types:

  • URL location (like, or http: // localhost: 13000 ).Internet Explorer sends a post message to the URL every time a change is made to enterprise mode fromToolsMenu.


The example will only work if you 've ve downloaded the sample discussed in the set up enterprise mode logging and Data Collection topic. if you don't have the sample, you won't have the web API.

  • Local Network Location (like, http ://Emieposturl/). Internet Explorer sends a post message to your specified local network location every time a change is made to enterprise mode fromToolsMenu.
  • Empty string. If you leaveValue DataBox blank; your employees will be able to turn enterprise mode on and off fromToolsMenu,But you won't collect any Logging Data.

If you do not need to collect logging information, you can setEmpty string.

After turn on local control of Enterprise mode so that your users can turn enterprise mode on fromToolsMenu.

Turning on this feature also addsEnterprise ModeProfile toEmulationTab Of the F12 Developer Tools.

2.2 set sitelist [5]

(1)To turn on Enterprise mode for all users on the PC:Open the Registry Editor-regedit.exe and goHKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode.

(2) editSiteListRegistry Key to point to where you want to keep your enterprise mode site list file. For example:

The content of value data can be in the following three forms:

  • HTTP Location:"Sitelist" = "http: // localhost: 8080/sites. xml"
  • Local Network:"Sitelist" = "\ Network \ shares \ sites. xml"
  • Local file:"Sitelist" = "file: // C: \ Users \ <user >\\ Documents \ testlist. xml"

Note:The value data in the image above is incorrect and should not contain the prefix "sitelist" =. The correct value data is shown in [6 ]:

Generally, HTTP Location is used, such as http: // localhost: 8080/testlist. xml.

3. How to add sites to the enterprise mode Site List

How to create the testlist. xml file above? Enterprise mode Site List Manager is required.

For details about how to download the enterprise mode Site List Manager, refer to [7 ].

For how to add sites to the enterprise mode site list, see [8 ]. After adding the file, create and save a testlist. xml file and save it to the default directory of localhost (such as htdocs directory under Apache) on the Local Web server ).

Note:Must be added to the enterprise mode Site List Manager. Editing only the testlist. xml file does not work.

4. Enterprise ModeVS Compatibility View

(1) Enterprise mode is turned on by IT managers using group policy settings for specific domains or pages. it's much like the Compatibility View settings, but provides Internet Explorer 8 compatibility. webpages that work in Internet Explorer 8 work seamlessly in enterprise mode [1 ].

Enterprise mode provide better compatibility.Some of the areas targeted by enterprise mode include [9 ]:

· User agent string differences. invalid legacy web apps use browser detection, not today's best practice of feature detection. by replicating the original Internet Explorer 8 user agent string, enterprise mode works for sites that fail if they can't recognize IE8 as the browser.

· ActiveX controls and other binaries. some ActiveX controls silently fail if they query the browser version and get a response they don't have CT, so enterprise mode appeases these by mimicking IE8's responses. in testing, customers report that contains of these ActiveX controls "just work" in enterprise mode.

· Deprecated functionality. internet Explorer 8 still contained some vestiges of proprietary functionality, such as CSS expressions which was used to place objects dynamically on a page. this functionality was removed in later versions of Internet Explorer, but some legacy web apps used this to place buttons and other elements. enterprise mode brings back some deprecated features, including CSS expressions.

· Pre-caching and pre-rendering. using modern browsers like Internet Explorer 11 pre-Cache and pre-render pages, to make browsing more fluid. when you click on a pre-cached link, one tab disappears while the pre-rendered content tab appears in its place. to a legacy navigation controls, this behavior is confusing-So enterprise mode turns it off.

Speaking of performance, we 've made a lot of browser improvements in the last five years; Internet Explorer 11 is dramatically faster than Internet Explorer 8. web apps load twice as fast, and enterprise mode takes advantage of network improvements, redesigned script and Layout engines, and hardware-accelerated graphics. while we believe that real-world performance matters when evaluating a browser, the Javascript benchmark results below highlight the significant difference between Internet Explorer 11 with enterprise mode and the original Internet Explorer 8. try it with your own apps, and see for yourself.

(2) They basically do the same thing, but enterprise mode does it better. compatibility View tells the browser to display the website's HTML and CSS in a way that previous versions of IE wocould, but does not execute code (like ActiveX controls) in the way that previous versions of IE wowould. so for a better level of compatibility, use enterprise mode. that's the theory of Compatibility View vs enterprise mode. in the real world, you will find that some websites work better with enterprise mode and some work better with Compatibility View. this will be a trial and error thing [10 ].

(3) compatibility mode will rendering in IE7 emulation mode by default, while enterprise mode will rendering in IE8 emulation mode. [11] [12 ].

5. Can webbrowser control be set to enterprise mode? 5.1 The precedence of the elements that determines the document mode

The precedence of the elements that determines the document mode (how the page will be rendered) are:

For ie:

X-UA-compatible> Compatibility View Settings> feature_browser_emulation> enterprise Mode

ForWeb browser control:
X-UA-compatible> feature_browser_emulation

Web browser controls do not support ie CV settings, including enterprise mode. I'm not aware of any way to opt-in. [13]

-> So Ie agent application cannot run a test in enterprise mode.

1.X-UA-compatible tag In a meta element or HTTP Response Header:

X-UA-compatible Value

Document Mode

Ie = 7

IE7 Mode

Ie = 8

IE8 Mode

Ie = 9

Ie9 Mode

Ie = 10

Ie10 Mode

Ie = 11

Ie11 Mode

Ie = edge

The highest supported document mode of the browser

2.Compatibility View settings:

If the web page is retrieved from a site in a domain on the Compatibility View list

Document mode is IE7 Mode

3.Feature_browser_emulation registry key:


Document Mode

Application Process key absent

IE7 mode (default)

Application Process key present

Based on the version of IE specified in the registry value

4.Enterprise Mode settings (only available in ie11 ):

If the enterprise mode is turned on and the web page is retrieved from a site on the Enterprise mode Site List

Document mode is IE8 Mode

5.2 can enterprise mode be set in IE 11 using HTML or Java?

I want to know how to set enterprise mode using HTML tags or Java's response header.

-> You Can't Do This. Websites can't ask to be rendered in this mode [14 ].
