I haven’t done much programming that makes use of the win32 types, but just from tech support and sysadmin type stuff I can confirm that DWORDs are still 32 bits. See them a lot in the Registry.
Given Window’s (sometimes questionable) attempts to maintain backwards compatibility, and the fact that a lot of the OS functionality and sysadmin tools are, at best, kludge built up in layers over decades on top of the old tools, I would strongly suspect that the win32 types are still the exact same size-wise despite the now 64-bit underlying architecture.
