Closing Control Panel, etc.

Can someone give me some code to close the following windows if they are open:

Control Panel
Printer Panel
Internet Explorer
Netscape Navigator
Netscape Communicator

I need to make a program to restrict access to certain functions, but i don't want to use registry, so i am gonna make a timer and every couple of seconds it will make a sweep and close any of the above windows if they are open. :)

Pleaze help me!

Thanxs alot!

Sorry, I don't have Netscape so I don't know the hWnd (class,caption) of it.

Code:
