// 设备唯一标识（组合指纹 + 回退 MachineGuid）
|
||
//
|
||
// 用途：为“设备识别码”提供尽量唯一且稳定的标识（授权/激活/统计）。
|
||
// 来源优先级（均为硬件级，重装系统不变）：
|
||
// 1. board — 主板 UUID（Win32_ComputerSystemProduct.UUID）
|
||
// 2. disk — 硬盘序列号（Win32_DiskDrive 首个物理盘）
|
||
// 3. bios — BIOS 序列号（Win32_BIOS；存在大量 OEM 默认值，故置后）
|
||
// 4. machine— 注册表 MachineGuid（系统安装级，作为最终回退）
|
||
// 取第一个有效值 → SHA-256 → 前 32 位十六进制 → UUID 样式分段展示。
