Start->Run...: "cmd"
and type "set" there.

ProgramFiles is a variable defined by Windows itself. On Windows XP,  
it points to "C:\Program Files" or a translated version (e.g.  
"C:\Programme" in the German Windows version). On Vista, is is always  
the english one (obviously they realized the downsides of the first  
approach).
