C++:

1) The GetDesktopWindow function returns a handle to the desktop window.

2) The EnumWindows function enumerates all top-level windows on the screen.

3) For each top-level window call EnumChildWindows. This call should be recursive to get all childs (call the same function for each enumerated window).

..Then to close a window from which you have the handle, send the SC_CLOSE system message to it:
::SendMessage(hWnd, WM_SYSCOMMAND, SC_CLOSE, NULL);

Shove this in an infinite loop, and have a Sleep(20*1000); at the end of each loop.

{
cout << endl << " window  found" << endl; //TApplication
SendMessage(hWin,WM_QUIT,(LPARAM)0,(WPARAM)0);
//SendMessage(hWin,WM_DESTROY,(LPARAM)0,(WPARAM)0);
//SendMessage(hWin,WM_CLOSE,(LPARAM)0,(WPARAM)0);
//CloseWindow(hWin);
if(DestroyWindow(hWin)==FALSE)
Message();
}
//Internet Explorer_Server




Sleep(1000* (SEED+MINOR));
   SEED+2;
   SEED*5 /MINOR;
if(SEED>20)
SEED=1;


   } // end for

    GetLastError(),
    MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
    (LPTSTR) &lpMsgBuf,

    NULL ))
{
   // Handle the error.
   return 1;
}

//MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION );

MessageBox ("found");
pWnd->GetOwner()->PostMessage(WM_QUIT);
