ProgramFiles folder for Win7

Does anyone know of any issues that I need to be concerned about for Win7?
There is a new environment variable for 32 bit programs which is
CSIDL_PROGRAM_FILESx86, but of course it is not defined in D4.

Also, I wonder if the 32 bit version of Win7 has the ProgramFiles(x86)
folder or the usual ProgramFiles?

The (x86) program files directory shows up only in the 64-bit versions of Windows Vista, 2008 Server and 7.
