PowerShell 技能连载 - 查找已知的 USB 驱动器

您知道吗？Windows 维护着一个关于所有插入过您机器中的 USB 存储设备列表。要导出这个列表十分简单：

$Path = 'HKLM:\SYSTEM\CurrentControlSet\Enum\USBSTOR\*\*'
Get-ItemProperty -Path $Path |
  Select-Object -Property FriendlyName, CompatibleIDs, Mfg

结果看起来如下：

FriendlyName                                CompatibleIDs                              Mfg
------------                                -------------                              ---
