## 下载可选功能离线安装媒体

在<https://my.visualstudio.com/Downloads>（无需 Visual Studio 付费订阅）搜索关键词`Features on Demand`或`Languages and Optional Features`寻找适用于当前 Windows 版本和架构的 ISO，下载并挂载它（文件资源管理器内打开，假设挂载到`X:\`，应该存在文件夹`X:\LanguagesAndOptionalFeatures`）。

## 检查当前系统可选功能安装情况

管理员终端执行：

```pwsh
Get-WindowsCapability -Online
```

## 安装特定可选功能

管理员终端执行：

```pwsh
Add-WindowsCapability -Online -Name "可选功能Name" -Source "X:\LanguagesAndOptionalFeatures" -LimitAccess
```

## 安装所有可选功能

管理员终端执行：

```pwsh
$sourcePath = "X:\LanguagesAndOptionalFeatures"

Get-WindowsCapability -Online |
    Where-Object { $_.State -eq 'NotPresent' } |
    ForEach-Object {
        Write-Host "Installing: $($_.Name)..." -ForegroundColor Cyan
        Add-WindowsCapability -Online -Name $_.Name -Source $sourcePath -LimitAccess
    }
```
