C ++ acquisition system version number

Because the system uses a version number, be treated differently.

    // 5.0 Windows 2000";
   // 5.1 Windows XP";
   // 5.2 Windows 2003";
   // 6.0 Windows Vista";
   // 6.1 Windows 7";
   // 6.2 Windows 8";
   // 6.3 Windows 8.1";
   // 10.0 Windows 10";
   //其他版本

method 1:

This method is a method of measuring down XP, win7, win10 are adopted.

DWORD Major,Minor,Build;
void GetOSVersion1()
{
    _asm
    {
        pushad
        mov ebx, fs:[0x18]; get self pointer from TEB
        mov eax, fs:[0x30]; get pointer to PEB / database
        mov ebx, [eax + 0A8h]; get OSMinorVersion
        mov eax, [eax + 0A4h]; get OSMajorVersion
        mov Minor, ebx
        mov Major, eax
        popad
    }
    Build = 0;
}

Method 2:

DWORD Major,Minor,Build;

typedef NTSTATUS(WINAPI* _NtQueryInformationProcess)
(_In_ HANDLE ProcessHandle, _In_ PROCESSINFOCLASS ProcessInformationClass,
    _Out_ PVOID ProcessInformation, _In_ ULONG ProcessInformationLength, _Out_opt_ PULONG ReturnLength);
_NtQueryInformationProcess NtQueryInformationProcess_;

DWORD GetProcessPEBAddress(HANDLE hProc)
{
    PROCESS_BASIC_INFORMATION peb;
    DWORD tmp;
    NtQueryInformationProcess_ = (_NtQueryInformationProcess)GetProcAddress(GetModuleHandle(L"ntdll.dll"), "NtQueryInformationProcess");
    NtQueryInformationProcess_(hProc, ProcessBasicInformation, &peb, sizeof(PROCESS_BASIC_INFORMATION), &tmp);
    return (DWORD)peb.PebBaseAddress;
}

void GetOSVersionByHandle(HANDLE handle)
{
    DWORD pebAddress = GetProcessPEBAddress(handle);
    DWORD OSMajorVersionAddress = pebAddress + 0x0a4;
    DWORD OSMinorVersionAddress = pebAddress + 0x0a8;
    DWORD OSBuildNumberAddress = pebAddress + 0x0ac;
    ReadProcessMemory(handle, (void*)OSMajorVersionAddress, &Major, sizeof(Major), 0);
    ReadProcessMemory(handle, (void*)OSMinorVersionAddress, &Minor, sizeof(Minor), 0);
    ReadProcessMemory(handle, (void*)OSBuildNumberAddress, &Build, sizeof(Build), 0);
}


void GetOSVersion2()
{
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, GetCurrentProcessId());
    GetOSVersionByHandle(handle);
}

Method 3:

GetVersionEx after the win10 version, it has failed.

Major DWORD, Minor, the Build; 

void GetOSVersion3 () 
{ 
    OSVERSIONINFO osvi;                     // definition of a data structure of the object OSVERSIONINFO 
    Memset (& osvi, 0 , the sizeof (OSVERSIONINFO));         // open space 
    osvi.dwOSVersionInfoSize = the sizeof (OSVERSIONINFO);     // define the size of 
    the GetVersionEx (& osvi);                     // version information 

    Major = osvi.dwMajorVersion; 
    Minor = osvi.dwMinorVersion; 
    the Build = osvi.dwBuildNumber; 
}
