Add-WindowsFeature 因意外路径而失败

Question

运行 Add-WindowsFeature 时发生以下错误：

PS C:\Users\pornograph> Add-WindowsFeature -Name "DSC-Service" -IncludeAllSubFeature -ErrorVariable errorVar
Add-WindowsFeature : The request to list features available on the specified server failed.
A DISM session could not be opened.
An error occurred. The directory in the temporary folder D:\TEMP\ could not be created.
Ensure that the path to the temporary folder exists and that you have Read/Write permissions on the folder. Error:
0x80070003
At line:1 char:1
+ Add-WindowsFeature -Name "DSC-Service" -IncludeAllSubFeature -ErrorVariable erro ...

    + FullyQualifiedErrorId : DISMAPI_Error__Failed_Opening_Dism_Session,Microsoft.Windows.ServerManager.Commands.AddWindowsFeatureCommand

从哪里來D:\TEMP\？

• 服务器没有 D:
• 没有以 D 开头的环境变量：
  • 机器TEMP和TMP=E:\TEMP
  • 用户和进程TEMP和TMP=C:\Users\etc.
• 操作系统 = Win 2012 R2 标准 x64
• $psversion表.psversion =4 0 -1 -1

Answer 1

（对原始问题的编辑似乎陷入了困境，因此再次发布：）

更新：它似乎在注册表中（很可能是在原始服务器映像中设置的）：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Microsoft-PowerShell-DSC-PullServer-Package~31bf3856ad364e35~amd64~en-US~6.3.9600.16384

InstallLocation="\\?\D:\temp\Dism\IDASF2ZC\{GUID}\"

整个HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing树由 TrustedInstaller 拥有（所有其他树 = 只读）。授予写入权限并更改值似乎没有带来任何变化（D:\TEMP仍在使用） - 是否需要重新启动某些东西才能读取新值？

不幸的是，以管理员身份运行不是一个选项。
