Make change in Internet option Automatically by Registery

Hi
I want to make some change in internet option , security tab:
Tools \ Internet Options \ Security \ Internet \ Sites \ Advanced ==
add a specific site to the zone.

Tools \ Internet Options\ Security \ Internet \ Custom Level:
* Initialize and script ActiveX controls not marked as safe for
scripting == Enable
* Automatic prompting for file downloads == Enable
* Allow script-initiated windows without size or position constraints
== Enable

*Use pop-up Blocker == Disable
* Display video and animation on a webpage that does not use external
media player == Disable
* only allow approved domains to use ActiveX without prompt
==Disable

How do i can this change Automatically by Registery.
Or:
i want make/use an application that makes these changes
automatically.

Thanks.
