使用 PowerShell 進行硬體資產調查

Windows 的 WMI, CIM 有很多資訊可以運用管理

例如軟硬體資產、系統資源效能、程式運作等

這次要做的是硬體資產調查，以前我有介紹使用 AIDA64 Business 來做資產調查，但這套軟體是要付費的。

所以不想要花錢，又要做到資產調查，就只好自己動作來

只要將 PowerShell 程式將資料寫入網芳檔案，使用群組政策，讓使用者開機就自動執行這個 PowerShell ，資料就會自動寫入檔案

$System = Get-CimInstance CIM_ComputerSystem

$BIOS = Get-CimInstance CIM_BIOSElement

$OS = Get-CimInstance CIM_OperatingSystem

$CPU = Get-CimInstance CIM_Processor

$HDD = Get-CimInstance Win32_LogicalDisk -Filter "DeviceID = 'C:'"

$EXTXT = "D:\Desktop\welp.txt"
