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. Damjan
