If you want a stupid joke I suggest recording 3 hours off irritating noises and setting this .wav as the windows-startupsound.
It's makes sound and is a stupid joke.

You need to create a windows application instead of a console application and just don't show a window. Easy greasy if you know how to make a windows application. :)

The only real difference is the starting point. Win32 programs use WinMain() as the starting point, and that keeps a console from being created. The source extension is still .cpp and the executable extension is still .exe.

#include <windows.h>

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow )
{
  MessageBox( NULL, "I'm a background program!", "Boo!", 0 );
}

That's the whole program. Just replace the MessageBox function with whatever logic you want. Maybe something like this.

#include <stdio.h>
#include <windows.h>

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow )
{
  while ( 1 )
    putchar( '\a' );
  return 0;
}

Once you build it you can put it in the startup folder and windows will run it automatically when the user logs in. If you put it in the all users startup folder, it will run when anyone logs in. That's a lot easier than trying to do it programmatically. ;)
