Thanks to @Kickaha's suggestion. Here's a simple method which checks the registry to see if it's set. Probably some cases where this could throw an exception so be sure to handle them.

    const string DWORD_FOR_ACTIVE_SCRIPTING = "1400";
    const string VALUE_FOR_DISABLED = "3";
    const string VALUE_FOR_ENABLED = "0";

    public static bool IsJavascriptEnabled( )
    {
        bool retVal = true;
        //get the registry key for Zone 3(Internet Zone)
        Microsoft.Win32.RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3", true);

        if (key != null)
        {
            Object value = key.GetValue(DWORD_FOR_ACTIVE_SCRIPTING, VALUE_FOR_ENABLED);
            if( value.ToString().Equals(VALUE_FOR_DISABLED) )
            {
                retVal = false;
            }
        }
        return retVal;
    }

Note: in the interest of keep this code sample short (and because I only cared about the Internet Zone) - this method only checks the internet zone. You can modify the 3 at end of OpenSubKey line to change the zone.
