   Windows released the memory when you shut the application down. 
   Unlike DOS, you are not working in a processor-controlled memory 
   space, it's a Windows-controlled memory space.
   You would only need to be concerned if you were using real mode 
   memory extensions such as EMS or XMS. But since you cannot use 
   such real mode structures from inside Windows, nothing to worry 
   about.
   But don't be tempted to forget about garbage collection on shut 
   down...it's still good practice to clean up after yourself...
