As far as I know, the main difference between Win64 and Win32 is different 
exception handling mechanism. In Win32, functions pushed and popped SEH 
frames; in Win64 exception handling is table-based: each function is 
associated with exception information table; it's documented in 
http://msdn.microsoft.com/en-us/library/7kcdt6fy%28v=VS.80%29.aspx). Win64 
differs from other x86-64 OSes in calling convention.
