Auto configuration settings for Internet Explorer 11
The Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022. For a list of what’s in scope, see the FAQ. The same IE11 apps and sites you use today can open in Microsoft Edge with Internet Explorer mode. Learn more here.
Automatic configuration lets you apply custom branding and graphics to your internal Internet Explorer installations, running on Windows 8.1 or Windows Server 2012 R2. For more information about adding custom branding and graphics to your IE package, see Customize the toolbar button and Favorites List icons using IEAK 11.
You'll only see and be able to use the IE Customization Wizard 11 - Automatic Configuration page if you're creating an internal IE installation package. For more information about the IE Customization Wizard 11 - Automatic Configuration page, see Use the Automatic Configuration page in the IEAK 11 Wizard.
Adding the automatic configuration registry key
For custom graphics and branding, add the
FEATURE\AUTOCONFIG\BRANDING registry key to your IE installation package.
Follow these directions carefully because serious problems can occur if you update your registry incorrectly. For added protection, back up your registry so you can restore it if a problem occurs.
To add the registry key
On the Start screen, type regedit, and then click Regedit.exe.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControlsubkey, point to New, and then click Key.
Enter the new key name,
FEATURE\AUTOCONFIG\BRANDING, and then press Enter.
FEATURE\AUTOCONFIG\BRANDING, point to New, and then click DWORD (32-bit) Value.
Enter the new DWORD value name, iexplore.exe, and then press Enter.
Right-click iexplore.exe, and then click Modify.
In the Value data box, enter 1, and then click OK.
Exit the registry editor.
Updating your automatic configuration settings
After adding the
FEATURE\AUTOCONFIG\BRANDING registry key, you can change your automatic configuration settings to pick up the updated branding.
Your branding changes won't be added or updated if you've previously chosen the Disable external branding of IE setting in the
User Configuration\Administrative Templates\Windows Components\Internet Explorer Group Policy object. This setting is intended to prevent branding by a third-party, like an Internet service or content provider. For more information about Group Policy, including videos and the latest technical documentation, see the Group Policy TechCenter.
To update your settings
Open the IE Customization Wizard 11, and go to the Automatic Configuration page.
Choose the Automatically detect configuration settings check box to allow automatic detection of browser settings.
Choose the Enable Automatic Configuration box to let you change the rest of the configuration options, including:

Automatic Configuration URL (.INS file) box: Type the location of your automatic configuration script.
Automatic proxy URL (.JS, .JVS, or .PAC file) box: Type the location of your automatic proxy script.
Internet Explorer 11 no longer supports using file server locations with your proxy configuration (.pac) files. To keep using your .pac files, you have to keep them on a web server and reference them using a URL, like
If your branding changes aren't correctly deployed after running through this process, see Auto configuration and auto proxy problems with Internet Explorer 11.
