推断Windows版本号新方法

#include "stdafx.h"
#include <iostream>
#include <windows.h>			// VersionHelpers.h 依赖于 windows.h
#include <VersionHelpers.h>     // Windows SDK 8.1 才有喔

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	// 是否大于等于 XP
	if (IsWindowsXPOrGreater())
		cout << ">= XP" << endl;
	else
		cout << " < XP" << endl;

	// 是否大于等于 XP SP1
	if (IsWindowsXPSP1OrGreater())
		cout << ">= XP SP1" << endl;
	else
		cout << " < XP SP1" << endl;

	// 是否大于等于 XP SP2
	if (IsWindowsXPSP2OrGreater())
		cout << ">= XP SP2" << endl;
	else
		cout << " < XP SP2" << endl;

	// 是否大于等于 XP SP3
	if (IsWindowsXPSP3OrGreater())
		cout << ">= XP SP3" << endl;
	else
		cout << " < XP SP3" << endl;

	// 是否大于等于 Vista
	if (IsWindowsVistaOrGreater())
		cout << ">= Vista" << endl;
	else
		cout << " < Vista" << endl;

	// 是否大于等于 Vista SP1
	if (IsWindowsVistaSP1OrGreater())
		cout << ">= Vista SP1" << endl;
	else
		cout << " < Vista SP1" << endl;

	// 是否大于等于 Vista SP2
	if (IsWindowsVistaSP1OrGreater())
		cout << ">= Vista SP2" << endl;
	else
		cout << " < Vista SP2" << endl;

	// 是否大于等于 Win8
	if (IsWindows8OrGreater())
		cout << ">= Win8" << endl;
	else
		cout << " < Win8" << endl;

	// 是否大于等于 Win8.1
	if (IsWindows8Point1OrGreater())
		cout << ">= Win8.1" << endl;
	else
		cout << " < Win8.1" << endl;

	// 是否为server版
	if (IsWindowsServer())
		cout << "server版" << endl;
	else
		cout << "非server版" << endl;

	// 以上的函数都是通过IsWindowsVersionOrGreater实现的
	// Windows 2000的版本为5.0，所以我们也能够直接通过版本推断
	if (IsWindowsVersionOrGreater(5, 0, 0))
		cout << ">= Win 2000" << endl;
	else
		cout << " < Win 2000" << endl;

	system("pause");
	return 0;
}

另外。假设将平台工具集选择为支持XP的话。就不能用上面的函数了，会提示找不到VersionHelper.h头文件。
