Microsoft 除了 CLI 的 WMIC 可以得到 WMI 資訊外，
PowerShell 也提供下列 WMI 指令

• Get-WmiObject
• Set-WmiInstance
• Invoke-WmiMethod
• Remove-WmiObject
• Register-WmiEvent

Get-WmiObject 用來取得 WMI 相關資訊，如無指定 Namespace 預設是 ROOT\CIMV2

簡單列出常用指令

1. 列出 Name Space
   Get-WmiObject -Class __namespace -Namespace root

只顯示Name
Get-WmiObject -Class __namespace -Namespace root | select name

2. 列出 Classes
   Get-WmiObject -List

List數量很多，分頁查看
Get-WmiObject -List | Out-Host -Paging

3. 列出 WMI Provider
   Get-WmiObject -Class __Win32Provider

4. 列出電腦系統資訊
   Get-WmiObject -Class Win32_ComputerSystem
   Get-WmiObject -Class Win32_ComputerSystem | Select-Object -Property SystemType
   Get-WmiObject -Class Win32_ComputerSystem | Select-Object -Property *

5. 列出 CPU 資訊
   Get-WmiObject -Class Win32_Processor

6. 列出 BIOS 資訊
   Get-WmiObject -Class Win32_BIOS

7. 列出 OS 資訊
   Get-WmiObject -Class Win32_Operatingsystem
   Get-WmiObject -Class Win32_OperatingSystem | Select-Object -Property *

8. 列出防毒資訊
   Get-WmiObject -Namespace root\SecurityCenter2 -Class AntiVirusProduct

9. 列出電腦桌面資訊
   Get-WmiObject -Class Win32_Desktop -ComputerName XXXXXXXX-PC

XXXXXXXX-PC 為本機系統關於中的裝置名稱
ComputerName 可以是 computer name, domain name, or IP Address,
Local localhost and 127.0.0.1.

列出 header 為 A到Z的所有資訊
Get-WmiObject -Class Win32_Desktop | Select-Object -Property [a-z]*

10. 列出本機服務
    Get-WmiObject -Query "Select * from Win32_Service"

列出開頭為 Win 的本機服務
Get-WmiObject -Query "Select * from Win32_Service Where Name Like 'Win%'"

如果應用上述指令寫 Powershell Script 執行時被系統 (Win 11) 阻擋，
需要設定 OS
System -> Privacy & security -> For developers -> PowerShell ->
Turn On "Change execution policy to allow local PowerShell scripts to run without signing. Require signing for remote scripts."

Microsoft Visual Basic Script 也可直接應用 GetObject來執行 WMI 指令
GetObject ("winmgmts:\" & ComputerName & "\ROOT\WMI")
