Event 1062 - Windows Reuse Navigation Restriction

Applies To: Windows 7, Windows Vista

To help prevent spoofing attacks, Windows® Internet Explorer® 8 prevents navigation from a top-level frame that is owned by one Web site to another Web site that is located within a different security context. In cases where this restriction takes effect, a new window or tab is opened rather than navigating in the existing frame. This change conforms to the HTML 5 draft specification for window navigation.

The security context of a source and a target frame are considered to be different from each other if the host name and the security zone are different.

When Is This Event Logged?

This event is logged when Internet Explorer forces a page to open in a new window because of a difference in security context.


For more information and examples, see the Event 1062-Windows Reuse Navigation Restriction topic from Internet Explorer Application Compatibility.


You can disable this security feature by setting the following named value in the registry:

  • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_Isolate_Named_Windows\iexplore.exe=0x00000000

What Happens If I Disable This Feature?

If you disable this security feature, you will be more prone to spoofing attacks. Disabling this feature should only be used as a temporary measure during troubleshooting, to compare the behavior of the application when the feature is enabled and when it is disabled. It is not recommended that this feature be left disabled on an ongoing basis.
