I noticed that as well when checking task manager. Interestingly, the file
versions numbers are exactly the same, despite the variances in the sizes of
those files.

Hi,
Only notepad.exe in \windows\syswow64 is 32-bit.
All the rest (start menu, \windows and \windows\system32) are 64-bit.

Yes, the version numbers are the same, since they're driven by the build
number.

Thank you everyone. After some research, I found that I can install x64
versions in a VM hosted by a 32-Bit OS. VMWare Server is free and it does
that. The free Microsoft Virtual PC doesn't support 64-Bit guest OS's.

Yes, that's true. But hardly the topic you asked about.
