求助！ win10 系统的计算机如何获得唯一的机器码？ Java 实现。

没有绝对的唯一

多获取几个硬件信息做哈希呗

MachineGuid ？

硬盘 id，实在不行上狗呗

靠直接获取硬件 id，应该没有绝对的唯一。

参考一下 intelliJ 的那些 IDE 做法？

wmic csproduct get UUID


wmic DISKDRIVE get SerialNumber

With our licensing tool we consider the following components

MAC Address
CPU (Not the serial number, but the actual CPU profile like stepping and model)
System Drive Serial Number (Not Volume Label)
Memory
CD-ROM model & vendor
Video Card model & vendor
IDE Controller
SCSI Controller
However, rather than just hashing the components and creating a pass/fail system, we create a comparable fingerprint that can be used to determine how different two machine profiles are. If the difference rating is above a specified tolerance then ask the user to activate again.

We've found over the last 8 years in use with hundreds of thousands of end-user installs that this combination works well to provide a reliably unique machine id - even for virtual machines and cloned OS installs.

唯一的机器码，会导致用户更改任何硬件都导致需要重新授权

这个网页提供了程序和 dll，但是没有提供源码

看这篇微软官方的文章吧。
