I think that it's highly more likely that the game will check the
windows version the standard way at install.  So as long as you pass
the version check there you'll be fine. Past that I don't see any
reason why they would code additional version checks after that. All
the games that I've seen don't do that.

If the game is standalone or runs without installing, then it would
probably just try to create the standard DX10 object that it needs. If
we provide it, then it will try to run. If not it will probably say it
needs DX10 or something. I don't see a reason why it needs* to check
the version of windows.

*But just you wait someone is bound to do it...
