   How do I change the GUI window look?
  Well I am making something like an updater and I was wondering how I can change the looking of my GUI window. Well by making a normal GUI u get a normal windowwith lookin up to ur WIndows preferances, the problem is that I wantthe Minimize Restore Down and Close button to display with the graphics I want tothe same for the bar on the top of the window, the same for the arround of the window. My GUI is in C++   
  You're probably looking for something like Windows Presentation Foundation(WPF).  This allows developers to create amazing looking GUI's for their windows applications, below is the link to the official description and introduction of WPF by Microsofthttp://msdn.microsoft.com/en-us/library/ms754130.aspx   ;  I'm not sure if you mean how to do it using the Win32 API. But using nothing but Win32 calls, the easiest way is to create your window with the WS_POPUP style, which will just give you an empty rectangle that is all client area. Paint it entirely yourself in WM_PAINT, both the client and nonclient areas, and handle the message WM_NCHITTEST correctly. WM_NCHITTEST asks the window's window procedure what part of the window a given point falls in.
