Binary Behavior Security
Microsoft Internet Explorer 6 for Windows XP Service Pack 2 (SP2). The FEATURE_BEHAVIORS allows Binary Behaviors to run more securely. When the feature is enabled, it can be set differently for each security zone by using the URL action flag URLACTION_BEHAVIOR_RUN. For more information, see About URL Security Zones.
By default, this feature is enabled for Windows Internet Explorer and for applications hosting the WebBrowser Control. To disable this feature by using the registry, add the name of your executable file to the following setting.
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
SOFTWARE
Microsoft
Internet Explorer
Main
FeatureControl
FEATURE_BEHAVIORS
contoso.exe = (DWORD) 00000000
The feature is enabled when the value is set to (DWORD) 00000001 and disabled when the value is (DWORD) 00000000.
Browser Emulation
Windows Internet Explorer 8 and later. The FEATURE_BROWSER_EMULATION feature defines the default emulation mode for Internet Explorer and supports the following values.
| Value | Description |
| 11001 (0x2AF9 | Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the declared !DOCTYPE directive. Failing to declare a !DOCTYPE directive causes the page to load in Quirks. |
| 11000 (0x2AF8) | IE11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11. |
| 10001 (0x2711) | Internet Explorer 10. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive. |
| 10000 (0x02710) | Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Default value for Internet Explorer 10. |
| 9999 (0x270F) | Windows Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the declared !DOCTYPE directive. Failing to declare a !DOCTYPE directive causes the page to load in Quirks. |
| 9000 (0x2328) | Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9.
Important In Internet Explorer 10, Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
|
| 8888 (0x22B8) | Webpages are displayed in IE8 Standards mode, regardless of the declared !DOCTYPE directive. Failing to declare a !DOCTYPE directive causes the page to load in Quirks. |
| 8000 (0x1F40) | Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8
Important In Internet Explorer 10, Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
|
| 7000 (0x1B58) | Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control. |

To control the value of this feature by using the registry, add the name of your executable file to the following setting and set the value to match the desired setting.
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
SOFTWARE
Microsoft
Internet Explorer
Main
FeatureControl
FEATURE_BROWSER_EMULATION
contoso.exe = (DWORD) 00009000
Child Window Clipping
Internet Explorer 9. Internet Explorer 9 optimized the performance of window-drawing routines that involve clipping regions associated with child windows. This helped improve the performance of certain window drawing operations. However, certain applications hosting the WebBrowser Control rely on the previous behavior and do not function correctly when these optimizations are enabled. The FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION feature can disable these optimizations.
By default, this feature is enabled for Internet Explorer and for applications hosting the WebBrowser Control. To disable this feature by using the registry, add the name of your executable file to the following setting.
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
SOFTWARE
Microsoft
Internet Explorer
Main
FeatureControl
FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION
contoso.exe = (DWORD) 00000000
The feature is enabled when the value is set to (DWORD) 00000001 and disabled when the value is (DWORD) 00000000.
Circular References in Script Management
Internet Explorer 8 and later. By default, Internet Explorer reduces memory leaks caused by circular references between Internet Explorer and the Microsoft JScript engine, especially in scenarios where a webpage defines an expando and the page is refreshed. If a legacy application no longer functions with these changes, the FEATURE_MANAGE_SCRIPT_CIRCULAR_REFS feature can disable these improvements.
By default, this feature is enabled for Internet Explorer and for applications hosting the WebBrowser Control. To disable this feature by using the registry, add the name of your executable file to the following setting.
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
SOFTWARE
Microsoft
Internet Explorer
Main
FeatureControl
FEATURE_MANAGE_SCRIPT_CIRCULAR_REFS
contoso.exe = (DWORD) 00000000
The feature is enabled when the value is set to (DWORD) 00000001 and disabled when the value is (DWORD) 00000000.
Note Because this feature improves the stability of Internet Explorer, disabling this feature is strongly discouraged.
Clipboard Script Control
When enabled, the FEATURE_ENABLE_SCRIPT_PASTE_URLACTION_IF_PROMPT feature allows scripts control over the Clipboard, even when the URLACTION_SCRIPT_PASTE URL action is set to "Prompt." This allows applications hosting the WebBrowser Control to opt out of a specific security check that may be unnecessary for the content displayed by the application. If the content is fully trusted and cannot be modified by any third-party, it may be safe to enable this feature. However, such a design decision should include a full security assessment. For more information, see Threat Modeling.
By default, this feature is disabled for Internet Explorer and enabled for applications hosting the WebBrowser Control. To enable this feature by using the registry, add the name of your executable file to the following setting.
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
SOFTWARE
Microsoft
Internet Explorer
Main
FeatureControl
FEATURE_ENABLE_SCRIPT_PASTE_URLACTION_IF_PROMPT
contoso.exe = (DWORD) 00000001
The feature is enabled when the value is set to (DWORD) 00000001 and disabled when the value is (DWORD) 00000000.
Controlling calls between Internet Explorer and ShellExecute
When the FEATURE_DISABLE_IE_SHELLEXECUTE_CALLS feature is enabled, an admin will be able to configure interaction from Internet Explorer (IE) web platform (WebPlat) binaries with the Windows Shell using the ShellExecute API.
Note
By default, calls from Internet Explorer components to ShellExecute using unregistered protocols are blocked.
Unregistered protocols: Identified scheme names that exist in the registry but do not have a URL Protocol sub-key or do not exist in the registry at all. Examples include: cpl, vbs
Registered protocols: Identified scheme names that exist in the registry and have a URL Protocol sub-key. Examples include: http, https, mailto,
Non-protocol ShellExecute calls: There is neither a URL nor a scheme name, but ShellExecute is being used to invoke a command.

Cross Domain Capture Event
The FEATURE_BLOCK_SETCAPTURE_XDOMAIN feature prevents capture events from being propagated to elements in webpages hosted on domains different than the one hosting the page containing the element that triggered the capture event.
