$hexPid=array(0xc2,0x49,0x4b,0xcc,0x60,0x34,0x09,0xcd,0x96,0xf7,0xec,0x94,0x0e,0x97,0x02);

修改为你的注册表中的DigitalProductId的偏移0x34到0x43的15个字节，导出到pid.reg，

然后拷贝到记事本，

c2,49,4b,cc,60,34,09,cd,96,f7,ec,94,0e,97,02

添加上0x，构造一个$hexpid数组。

$hexPid=array(0xc2,0x49,0x4b,0xcc,0x60,0x34,0x09,0xcd,0x96,0xf7,0xec,0x94,0x0e,0x97,0x02);

注册表位置：

\\HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion 中的DigitalProductId 值。
