如何使用PowerShell刪除用戶配置文件

Question

我有以下腳本。如果我取消註釋行註釋#3，我得到的錯誤

Exception calling "Delete" with "0" argument(s): "" 
At Z:\Scripts\Powershell\Remove-UserProfile.ps1:48 char:21 
+      $Profile.Delete() 
+      ~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : NotSpecified: (:) [], MethodInvocationException 
    + FullyQualifiedErrorId : DotNetMethodException 

不管WMI使用格式#1或#2我是否審問。如果我離開#3評論，並取消#4，我得到的錯誤

Remove-WmiObject : 
At Z:\Scripts\Powershell\Remove-UserProfile.ps1:49 char:21 
+      Remove-WmiObject -InputObject $Profile 
+      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : InvalidOperation: (:) [Remove-WmiObject], COMException 
    + FullyQualifiedErrorId : RemoveWMICOMException,Microsoft.PowerShell.Commands.RemoveWmiObject 

不管查詢字符串Get-WMIObject的。

我在網上可以找到的所有東西 - 包括其他一些SO問題 - 意味着這兩種方法都可以工作，但似乎都不行。我已檢查目標配置文件是否已加載，但不是。爲什麼我不能使用WMI來刪除用戶配置文件？我能做些什麼確實工作，並且不涉及從第三方下載實用程序（這是我們的「信息安全」團隊所不允許的）？

#4     Remove-WmiObject -InputObject $Profile 
       }
