how to add "create automatic configuration script" url via gpo for IE 10

Hello,

I have win 8 clients and DC with win 2008 sp2.

I do want to push out proxy configration script to IE 10 and looks like there is another way via preferences to achieve this.

How exactly should I be doing this, So far I had done this via old way and its no longer working:

User configuration > Windows Settings > Internet Explorer Maintenance > Connection > Automatic Browser Configuration. : Select Enable Automatic Configuration.

Thanks
