We're getting into very compiler-specific things here, which should probably 
go into one of the Microsoft groups.  However, a quick test here on my copy 
of Visual Studio shows that even the "release" version defaults to having 
debug info generated.

Right-click the project, select "properties".  Then, under configuration 
properties, linker, debugging, make sure "generate debug info" is set to "no".

If there are still some "private" things remaining, you may walso want to 
set configuration properties, linker, manifest file, generate manifest to 
"no".  (No path names were in my test .exe within the manifest.  YMMV.)
