Windows8でのGetVersionEx
実行されているOSを判別するためのC++コードを書いています。私はそれを行うためにGetVersionEx() APIを使用し、チュートリアルとして このコード を使用しますが、Windows8を処理していないようです。Windowsで実行するように修正する方法を知っている人はいますか8？
MSDNフォーラムのいくつかのコメントによると この記事 Windows8のバージョン番号は6.2です
これは、Windows 8 DeveloperPreviewで更新およびテストされたサンプルコードです。

OK、私は誰かがすでにこれをしていることを望んでいました...しかし、私はそうは思わないので、ここに行きます：

//OSVERSIONINFO for GetVersionEx returns:
dwMajorVersion = 6;
dwMinorVersion = 2;
wProductType = 1;
//GetProductInfo returns:
dwType = 0x4A; //Not documented yet???
PS。 VS IDEがインストールされていません。それらを取得するために小さなアプリを作成する必要がありました...
システムの基本的な（メジャー、マイナー）検証のための別の可能な方法ですが、製品の詳細は詳細ではありません。コアシステムファイルのバージョン（例kernel32.dll）を確認することです。

このMSDNページ によると、実行中のWindowsバージョンを判別するには、実際にはGetVersionInfoExの代わりにバージョンヘルパー関数を使用することをお勧めします。 GetVersionEx ページで説明されているように、そのAPIは将来消滅する可能性があります。
Windows8は6.2です。
Windows Server2012も6.2です。
