Wired and wifi connections to the Internet at the same time?

Hi all :)
i use a laptop that has Ethernet and WiFi cards.
usually i use WiFi only as default internet source , but when i connect the Ethernet cable-> the WiFi network doesn't stop or shut down automatically.
-in such situation does really 2 network act parallel?
-is there a way to "tell" windows that when Ethernet network is on , WiFi network adopter will close it self?
(i don't want to Disabling/enabling in device manager every time)
Thanx!

edit:
i tried this but didn't work ...

"You can change the order, in which Windows connects to different network adapters, to do this go to the Network Connections window, there

1. press Alt
2. select Advanced > Advanced connections
3. open the Adapters and Bindings Tab

There you can change the order of the network adapters, in your case, try placing your LAN connection to the top of the list, this should cause windows to use the braodband Ethernet connection when it's available and only go via wireless when not."
