The heuristic isn't "app works on this Windows version", it's "app is
designed for this Windows version". If a heuristic tells you a game
needs 98 when it needs XP, the heuristic is broken, even if the game
works better in 98 because it doesn't load a driver.
Also, the existence of driver loading APIs in DLL imports is probably
a good heuristic to tell that an app needs XP.
