A memory (RAM) problem with the Common Dialog Boxes library in the Win32 API

Captain Price asked:

I know some programming (C/C++, JAVA, Win32..), but I don't know advanced concepts of Computer Science. I just know the basics. This question is about memory management in Windows Operating Systems. You can see the problem by just observing.

1. Open a file using Notepad by double clicking a file.
2. Open the Task Manager, and under processes tab you'll find the memory taken by the Notepad.exe (it is about 1,400 K)
3. Then open a file using the Common Dialog Boxes Library which is used in Notepad (Goto File --> Open).
4. Now you'll see the memory taken by Notepad.exe in the Task Manager as about 8,000 K.

Why is that ? And Even After when closing the Open File Dialog, the memory will not change. Why isn't Windows (or the library or anything else) freeing the memory after closing the Open File Dialog.

Need a good Answer !

[I'm using Win7 64bit)
