Sounds like you're talking about WOW6432. If I'm not mistaken, it

Sounds vaguely familiar.

involved a whole set of duplicate libraries and some duplicate
utilities. C:\Windows\System contained only the 64-bit versions; C:
\Windows\System32 contained 32-bit versions.

This is analogous to "C:\Program Files" and "C:\Program Files (x86)"
for user-installed programs in 64-bit Windows, though of course there
would generally be no duplication of programs. It's possible to
install 32-bit _and_ 64-bit Firefox if you want to, but I imagine
that's pretty rare. (In my case, I found out it was possible by
carelessly downloading and installing the wrong update.)

Whatever it was, they apparently pulled it at the last moment (so they
told me in the Turnpike 'group).
