I think think would remove a lot of headaches.  Downloading and
installing the Platform SDK should not be an issue, imo.

The only problem that I see is this:

I'm not sure the platform SDK include files (.H and .IDL) are really
compatible with VC7.1.  I remember that we (on our company, building C++
software) had to 'Unregister the PSDK Directories with Visual Studio'
(available from the start menu) before building the stuff, otherwise
there were compiler errors.
