Windows 10 PowerShell Get-WindowsCapability 和 Add-WindowsCapability 命令出错

Question

我正在运行 Windows 10 Pro 1809
我希望在计算机上安装 Active Directory；但是，当我尝试使用 powershell 命令时：

Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability -Online

我收到以下错误：

Add-WindowsCapability : Add-WindowsCapability failed. Error code = 0x800f0950
At line:1 char:45
+ ... WindowsCapability -Name RSAT* -Online | Add-WindowsCapability -Online
+                                             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Add-WindowsCapability], COMException
    + FullyQualifiedErrorId : Microsoft.Dism.Commands.AddWindowsCapabilityCommand

还值得注意的是该命令：

Get-WindowsCapability -Name RSAT* -Online | Select-Object -Property DisplayName, State

显示以下内容：

DisplayName                                                                          State

Answer 1

尝试这个：

使用管理员权限打开 Powershell 并添加以下内容：

将 Windows 更新服务器密钥设置为 0

Set-ItemProperty -Path HKLM:SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU -Name UseWUServer -Value 0

重新启动Windows更新服务

Restart-Service -Name wuauserv -Force

获取 RSAT 工具

Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability -Online

将 Windows 更新服务器密钥设置为 1

Set-ItemProperty -Path HKLM:SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU -Name UseWUServer -Value 1

重新启动Windows更新服务

Restart-Service -Name wuauserv -Force

完毕

Answer 2

显然，错误代码 0x800f0950 表示“没有足够的源来安装某些内容”，一个或多个 RSAT 工具可能需要 .NET 3.5，这需要安装其他源。请检查您是否安装了 .NET 3.5，如果没有安装，然后再次运行 RSAT 安装。
