怎么判断win7 sp0还是win7 sp1!

[花熊]

怎么判断win7 sp0还是win7 sp1!，我知道用winver可以看到版本号比如6.1是win7 sp1，

win7sp0 :(g_OSVersionInfo.dwMajorVersion == 6 && g_OSVersionInfo.dwMinorVersion == 0)????
win7sp1 :(g_OSVersionInfo.dwMajorVersion == 6 && g_OSVersionInfo.dwMinorVersion >= 1)????

是上面这样判断吗，做过的XDGM给个明确的答案吧，这个很纠结啊，在线等.

这个认真看看MSDN就知道的吧

typedef struct {

DWORD dwOSVersionInfoSize;       //在使用GetVersionEx之前要将此初始化为结构的大小

DWORD dwMajorVersion;               //系统主版本号

DWORD dwMinorVersion;               //系统次版本号

DWORD dwBuildNumber;               //系统构建号

DWORD dwPlatformId;                  //系统支持的平台(详见附1)

TCHAR szCSDVersion[128];          //系统补丁包的名称

WORD wServicePackMajor;            //系统补丁包的主版本

WORD wServicePackMinor;            //系统补丁包的次版本

WORD wSuiteMask;                      //标识系统上的程序组(详见附2)

BYTE wProductType;                    //标识系统类型(详见附3)

BYTE wReserved;                         //保留,未使用

} OSVERSIONINFOEX, *POSVERSIONINFOEX;

这3个字段

szCSDVersion
A null-terminated string, such as "Service Pack 3", that indicates the latest Service Pack installed on the system. If no Service Pack has been installed, the string is empty.

wServicePackMajor
The major version number of the latest Service Pack installed on the system. For example, for Service Pack 3, the major version number is 3. If no Service Pack has been installed, the value is zero.

wServicePackMinor
The minor version number of the latest Service Pack installed on the system. For example, for Service Pack 3, the minor version number is 0.

另外
vista/2008 :(g_OSVersionInfo.dwMajorVersion == 6 && g_OSVersionInfo.dwMinorVersion == 0)
win7/2008 R2 :(g_OSVersionInfo.dwMajorVersion == 6 && g_OSVersionInfo.dwMinorVersion >= 1)

[stjay]

win7/2008 R2 :(g_OSVersionInfo.dwMajorVersion == 6 && g_OSVersionInfo.dwMinorVersion >= 1)

还有win8，是6.2
win2012应该也是6.2

回楼上的，我在winsp1下做了测试代码：

OSVERSIONINFOEX osvi;
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
GetVersionEx((OSVERSIONINFO*)&osvi);

结果得到的szCSDVersion字段为空，wServicePackMajor为0，而用winver看到的明显是sp1，所以那个方法不正确

我需要确认win7 sp0, sp1的判断是怎么写的，

自测试错误，sorry,
