早期沒有可以直接取得OS version的方式，
但有GetVersionEx可以得知一些資訊：
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724451(v=vs.85).aspx
可以參考MSDN這張表自定義function：
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724834(v=vs.85).aspx
可以把這個C#給改了：
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724429(v=vs.85).aspx
但有了新版本就得記得更改此function
還好Delphi6可以用啊……
