On the contrary, I think perhaps the best thing for the preservation of the history of windows gaming is for windows to stop changing. A frozen or deprecated win32 API will give WINE (which is already quite good) breathing room to catch up and fill in the gaps, without having to continuously cope with the shifting sand of the latest experiments with windows. We'll be able to run old windows games forever, rather than just as long as Microsoft deigns to allow it. DOS games are fairly well preserved at this point for similar reasons.
Of course, then we'll have to deal with whatever the next platform is, but that's just the reality of the industry.
