我将从我刚刚为 SO 问题所做的答案中复制粘贴一些代码。我遇到的问题是为什么Invoke-WmiMethod在 Windows 8（PS3.0）上工作时在我的 Windows 7（PS2.0）机器上返回错误。这是代码：

#Username/Group to give permissions to
$trustee = ([wmiclass]'Win32_trustee').psbase.CreateInstance()
$trustee.Domain = "domainname"
$trustee.Name = "username"

#Accessmask values
$fullcontrol = 2032127
$change = 1245631
$read = 1179785

#Create access-list
$ace = ([wmiclass]'Win32_ACE').psbase.CreateInstance()
$ace.AccessMask = $fullcontrol
$ace.AceFlags = 3
$ace.AceType = 0
$ace.Trustee = $trustee

#Securitydescriptor containting access
$sd = ([wmiclass]'Win32_SecurityDescriptor').psbase.CreateInstance()
$sd.ControlFlags = 4
$sd.DACL = $ace
$sd.group = $trustee
$sd.owner = $trustee

#Arguments - Arguments: access, description, max. allowed, name, password, path, type(0 = drive/folder share)
Invoke-WmiMethod -Class Win32_Share -Name Create -ArgumentList @($sd, "TestDescription", 100, "TestName$", "", "C:\Test", 0)

Invoke-WmiMethod在 Windows 7 机器上执行时返回错误，而在 Windows 8 上工作正常。如果我$sd用 $null 替换（访问参数）它在 win7 上运行良好。错误是：

Invoke-WmiMethod <<<< -Class win32_share -name Create -ArgumentList @($sd, "TestDescription", 100, "TestName$", "", "C:\Test", 0) 
+ CategoryInfo : InvalidOperation: (:) [Invoke-WmiMethod], ManagementException + FullyQualifiedErrorId : InvokeWMIManagementException,Microsoft.PowerShell.Commands.InvokeWmiMethod'

这是使用的参数列表Invoke-WmiMethod：

PS C:\Windows> ([wmiclass]'win32_share').GetMethodParameters('create')

__GENUS          : 2
__CLASS          : __PARAMETERS
__SUPERCLASS     : 
__DYNASTY        : __PARAMETERS
__RELPATH        : 
__PROPERTY_COUNT : 7
__DERIVATION     : {}
__SERVER         : 
__NAMESPACE      : 
__PATH           : 
Access           : 
Description      : 
MaximumAllowed   : 
Name             : 
Password         : 
Path             : 
Type             : 
PSComputerName   :

谁能帮我理解为什么Invoke-WmiMethod在 w8 上工作时不喜欢我在 w7 上的访问参数？如果我运行它，它接受$sd两者：([wmiclass]'Win32_share').Create(.....)使用它的定义：

PS C:\Windows> ([wmiclass]'win32_share').Create
