That's a windows issue. When they say dword, they actually mean 32bit. It's just a type alias. I assume you will find the same issue on the Window NT ports to MIPS and PowerPC. Where you see dword as 64bit on those platforms is their documentation and assembly syntax. Most software in higher level languages (that aren't windows) avoided naming their type alias as WORD, DWORD and QWORD.
