使用PowerShell 自动安装VC++补丁

执行环境：Windows Server 2012 R2

VC++下载链接

这里有个问题，虽说可以静默安装，但是未对当前系统检测是否已安装vc++补丁，望大佬指点

# 自动安装
Set-ExecutionPolicy -Force remotesigned
# 获取当前脚本绝对路径
$path = Split-Path -Parent $MyInvocation.MyCommand.Definition;
$Net = "\vcredist_x64.exe";
Set-Location $path;

function Show-Progress ($file, $arguments){
    $process = Start-Process $file $arguments -Verb RunAs -PassThru
    for($i = 0; $i -le 100; $i = ($i + 1) % 100)
    {
        Write-Progress -Activity "正在安装 C++补丁" -PercentComplete $i
        Start-Sleep -Milliseconds 100
        if ($process.HasExited) {
            Write-Progress -Activity "Installer" -Completed
            if ($process.HasExited) {
                # 提示安装状态
                if ($process.ExitCode -ne 0) {
                    Write-Warning "安装过程返回错误代码: $($process.ExitCode)";
                }else {
                    Write-Host "成功安装C++补丁。"
                }
                break
            }
        }
    }
}
function InstallNet ($filepath,$filename){
    $NetFxPath = $filepath + $filename;
    #验证安装文件是否存在
    If(Test-Path -Path $NetFxPath) {
        Write-Host "正在安装 C++补丁 ..."
        Show-Progress $NetFxPath "/q /norestart"
    }
    Else {
        Write-Warning "找不到C++补丁安装包。"
    }
}
