WMI是Windows管理規(guī)范的縮寫，其中包含很多系統(tǒng)的軟硬件信息。而Windows用戶信息也可以通過WMI對象來獲取。PowerShell提供了對WMI的訪問功能，十分方便且強大——這就是Get-WmiObject這個cmdlet。
Get-WmiObject -Class Win32_UserAccount -Filter "Name='$env:username' and Domain='$env:userdomain'"
Get-WmiObject -Class Win32_UserAccount -Filter "Name='$env:username' and Domain='$env:userdomain'" | Select-Object *
