64-bit mode should (in theory) run 99% of 32-bit programs fine, though
that assumes you install the 32-bit Windows subsystem (which is
optional for servers, or so I heard). However, I wouldn't say
everything works. Rumor says that even MSVC 2k5 didn't run atop Vista
when it was first released, and I have no idea if they ever fixed
that. So compatibility issues will always exist, even without AMD64.
Presumably APIs change or drivers break or DLLs have regressions, etc.
Nothing is totally foolproof.

But yes, in my experience, almost all Win32 apps run fine atop Win64
(though that is not exhaustive, my tests are very very limited since
there are thousands of apps out there).
