我在docker中运行microsoft/windowsservercore:1803：
docker run -it microsoft/windowsservercore:1803
在其中，我启动 powershell 并运行Get-WindowsCapabilitycmdlet 并得到以下输出：
PS C:\> Get-WindowsCapability -online
Get-WindowsCapability : The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
At line:1 char:1
+ Get-WindowsCapability -online
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-WindowsCapability], COMException
+ FullyQualifiedErrorId : Microsoft.Dism.Commands.GetWindowsCapabilityCommand
它指的是什么服务？我可以设置容器以便允许我运行该服务或Add-WindowsCapabilitycmdlet 吗？
最终，我想要运行[微软官方分发的] OpenSSH 服务器。
更新。我检查了容器中的 Windows Update 和 TrustedInstaller 服务的状态（正如评论中所建议的那样）：前者已被禁用，因此我启用了它：
Set-Service -Name wuauserv -StartupType Manual
Start-Service -name wuauserv
然后再次尝试运行Get-WindowsCapability：
PS C:\> Get-WindowsCapability -online
Get-WindowsCapability : Get-WindowsCapability failed. Error code = 0x80d03805
At line:1 char:1
+ Get-WindowsCapability -online
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-WindowsCapability], COMException
+ FullyQualifiedErrorId : Microsoft.Dism.Commands.GetWindowsCapabilityCommand
仍然不起作用，但是错误现在不同了。
这是我在 EventLog 中看到的内容：
