I was looking at some libraries with dumpbin and I noticed that all the 64-bit versions were linked to KERNEL32. Is there no KERNEL64 on 64-bit Windows? If not, why?
All my operating systems are 32-bit so I can't just look. A google search brings up nothing worthwhile so I suspect that there is no KERNEL64 but I'm still curious as to why this is.
EDIT: I found this later which is pretty useful. MSDN guide to x64
It's always called kernel32.dll, even on 64-bit windows. This is for the same compatibility reasons that system32 contains 64-bit binaries, while syswow64 contains 32-bit binaries.
On the 64-bit versions of Windows one of the "kernel32.dll"s contains 64-bit code but is still called kernel32.dll. This is at least misleading
Hope the following links will give the solution for this

64-bit Windows provides such an environment "out of the box" and supports 32-bit applications using the 'Windows on Windows 64' subsystem, abbreviated to WOW64, which runs in user mode and maps the 32-bit calls to the operating system kernel into an equivalent 64-bit call. This is normally almost invisible to the calling program.Windows provides a set of 64-bit DLLs in %windir%\system32 and an equivalent set of 32-bit DLLs in %windir%\syswow64. In fact the bulk of the binary images in this directory are identical to the same files in the system32 directory on a 32-bit Windows installation. (It seems to me an unfortunate naming issue that the 64-bit DLLs live in system32 and the 32-bit ones live in syswow64, but there it is)
