C++检查Windows10

Question

我正在制作一个针对特定操作系统的应用程序，但我似乎无法缩小Windows 10的范围，它出现在Windows 8上。我在Window 10专业版上进行了测试，结果是重大:6分钟:2。有没有其他方法可以更有效地检查它是不是windows 10？

编辑:找到了一个可以正常工作的接口RtlGetVersion()可以在所有操作系统上正常工作！

#include "windows.h"
#include <iostream>
using namespace std;
BOOL EqualsMajorVersion(DWORD majorVersion)
{
OSVERSIONINFOEX osVersionInfo;
::ZeroMemory(&osVersionInfo, sizeof(OSVERSIONINFOEX));
osVersionInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osVersionInfo.dwMajorVersion = majorVersion;
ULONGLONG maskCondition = ::VerSetConditionMask(0, VER_MAJORVERSION, VER_EQUAL);
return ::VerifyVersionInfo(&osVersionInfo, VER_MAJORVERSION, maskCondition);
}
BOOL EqualsMinorVersion(DWORD minorVersion)
{
OSVERSIONINFOEX osVersionInfo;
::ZeroMemory(&osVersionInfo, sizeof(OSVERSIONINFOEX));
osVersionInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osVersionInfo.dwMinorVersion = minorVersion;
ULONGLONG maskCondition = ::VerSetConditionMask(0, VER_MINORVERSION, VER_EQUAL);
return ::VerifyVersionInfo(&osVersionInfo, VER_MINORVERSION, maskCondition);
}
int main()
{
    if (EqualsMajorVersion(7) && EqualsMinorVersion(1))
        printf("Maj:7 Min:1");
    else if (EqualsMajorVersion(7) && EqualsMinorVersion(0))
        printf("Maj:7 Min:0");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(7))
        printf("Maj:6 Min:7");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(6))
        printf("Maj:6 Min:6");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(5))
        printf("Maj:6 Min:5");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(4))
        printf("Maj:6 Min:4");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(3))
        printf("Maj:6 Min:3");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(2))
        printf("Maj:6 Min:2");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(1))
        printf("Maj:6 Min:1");
    else if (EqualsMajorVersion(6) && EqualsMinorVersion(0))
        printf("Maj:6 Min:0");
    else if (EqualsMajorVersion(5) && EqualsMinorVersion(2))
        printf("Maj:5 Min:2");
    else if (EqualsMajorVersion(5) && EqualsMinorVersion(1))
        printf("Maj:5 Min:1");
    else
        printf("OS not on list...");
    getchar();
}

Answer 1

这很讽刺但是..。

BOOL WINAPI IsWindows10OrGreater(void);

Docs here。

编辑：来自Redmond的天才们似乎在思考原型时遇到了问题，或者换句话说，OP得到了评论中所述的未定义的符号错误。还有这个函数：

BOOL WINAPI IsWindowsVersionOrGreater(
    WORD wMajorVersion,
    WORD wMinorVersion,
    WORD wServicePackMajor
);

而且，对于Windows10，wMajorVersion、wMinorVersion和wServicePackMajor似乎分别是10、0和0。

该函数here的文档。

Second edit：这是官方的：IsWindowsVersionOrGreater()和GetVersionEx()从8.1开始就被打破了。请始终使用IsWindowsXXXOrGreater()，其中XXX可以是XP、XPSP1、XPSP2、XPSP3、Vista、VistaSP1、VistaSP2、<代码>D25、<代码>D26、<代码>D27、<代码>D28、<代码>D29或<代码>D30。

下面的内容对我很有效：

.
.
.
#include <windows.h>
#include <stdio.h>
#include <tchar.h>
.
.
.

typedef void (WINAPI * RtlGetVersion_FUNC) (OSVERSIONINFOEXW *);
BOOL GetVersion(OSVERSIONINFOEX * os) {
    HMODULE hMod;
    RtlGetVersion_FUNC func;
#ifdef UNICODE
    OSVERSIONINFOEXW * osw = os;
#else
    OSVERSIONINFOEXW o;
    OSVERSIONINFOEXW * osw = &o;
#endif

    hMod = LoadLibrary(TEXT("ntdll.dll"));
    if (hMod) {
        func = (RtlGetVersion_FUNC)GetProcAddress(hMod, "RtlGetVersion");
        if (func == 0) {
            FreeLibrary(hMod);
            return FALSE;
        }
        ZeroMemory(osw, sizeof (*osw));
        osw->dwOSVersionInfoSize = sizeof (*osw);
        func(osw);
#ifndef UNICODE
        os->dwBuildNumber = osw->dwBuildNumber;
        os->dwMajorVersion = osw->dwMajorVersion;
        os->dwMinorVersion = osw->dwMinorVersion;
        os->dwPlatformId = osw->dwPlatformId;
        os->dwOSVersionInfoSize = sizeof (*os);
        DWORD sz = sizeof (os->szCSDVersion);
        WCHAR * src = osw->szCSDVersion;
        unsigned char * dtc = (unsigned char *)os->szCSDVersion;
        while (*src)
            * Dtc++ = (unsigned char)* src++;
        *Dtc = '\ 0';
#endif

    } else
        return FALSE;
    FreeLibrary(hMod);
    return TRUE;
}

.

//check win10
void mymethod() {

OSVERSIONINFOEX os;

    if (GetVersion(&os) == TRUE && os.dwMajorVersion == 10)
    {
        isWin10 = TRUE;
    }

}

更新:已检查win7、win8.1和win10。现在一切都确定了。所以代码：

#include <windows.h>
#include <VersionHelpers.h>
#include <string>

std::string getWinVerion() {

OSVERSIONINFO info;
ZeroMemory(&info, sizeof(OSVERSIONINFO));
info.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);

GetVersionEx(&info);

std::string version = std::to_string(info.dwMajorVersion);
version.append(".").append(std::to_string(info.dwMinorVersion));

if (IsWindows7SP1OrGreater()) {
    if (version == "6.1")
        return "6.1";
}

if (IsWindows8Point1OrGreater())
    return "6.3";
else
    return "10.0";
}
