硬盘序列号的获取
MSDN中利用WMI方法获取到的硬盘序列号，可不可以作为电脑的唯一标识符？

用汇编获取cpu id号吧，似乎奔腾4后每个cpu id号都是唯一的，这可以用来做序列号。以下是别人写的代码：
#include<iostream>
#include <string>
using namespace std;
string GetCPUID()
{
char str[256];
string CPUID;
unsigned long s1,s2;
unsigned char vendor_id[]="------------";
char sel;
sel='1';
string VernderID;
string MyCpuID,CPUID1,CPUID2;
switch(sel)
{
case '1':
__asm{
xor eax,eax //eax=0:取Vendor信息
cpuid //取cpu id指令，可在Ring3级使用
mov dword ptr vendor_id,ebx
mov dword ptr vendor_id[+4],edx
mov dword ptr vendor_id[+8],ecx
}
sprintf(str,"%s",vendor_id);
VernderID = str;
printf("%s:productor\n",str);
//VernderID.Format("%s-",vendor_id);
__asm{
mov eax,01h //eax=1:取CPU序列号
xor edx,edx
cpuid
mov s1,edx
mov s2,eax
}
sprintf(str,"%08X%08X",s1,s2);
CPUID1 = str;
printf("%s:cpu2\n",str);
//CPUID1.Format("%08X%08X",s1,s2);
__asm{
mov eax,03h
xor ecx,ecx
xor edx,edx
cpuid
mov s1,edx
mov s2,ecx
}
sprintf(str,"%08X%08X",s1,s2);
CPUID2 = str;
printf("%s:cpu2\n",str);
//CPUID2.Format("%08X%08X",s1,s2);
break;
case '2':
{
__asm{
mov ecx,119h
rdmsr
or eax,00200000h
wrmsr
}
}
printf("CPU id is disabled");
//AfxMessageBox("CPU id is disabled.");
break;
}
MyCpuID = CPUID1+CPUID2;
CPUID = MyCpuID;
return CPUID;
}
int main()
{
cout << GetCPUID() << endl;
return 0;
}
