Visual Studio Express is a Visual Studio 2005 IDE system for XP 
with some features disabled, the disabled features include 
interactive debugging, help, online news/blog stuff, etc: 
advanced IDE features.

AFAIK the compilers are intact and can be used on the command line
as well as from the IDE. I think you do need to download 
the platform SDK separately though. AFAIK on x86_64 platform,
VS is a 32 bit program, as are the compilers, but they can
generate 64 bit code (the 32 and 64 bit compilers are separate
executables and run in distinct environments .. )

One thing to watch though: embedded assembler is gone in new
MSVC++ compilers (due to multi-arch support I guess).
However assembler works in 64 bit, Ocaml 64 bit for Windows uses it.
