是否可以通过Powershell在多个远程服务器上安装Windows更新？

# 定义远程服务器列表
$servers = @("Server1", "Server2", "Server3")

# 启用远程管理
Enable-PSRemoting -Force

# 在每个服务器上安装更新
foreach ($server in $servers) {
    Write-Host "Installing updates on $server..."
    Invoke-Command -ComputerName $server -ScriptBlock {
        # 检查并安装更新
        $updateSession = New-Object -ComObject Microsoft.Update.Session
        $searcher = $updateSession.CreateUpdateSearcher()
        $searcher.Online = $true
        $result = $searcher.Search("IsInstalled=0 and Type='Software'")
        
        if ($result.Updates.Count -gt 0) {
            $installer = $updateSession.CreateUpdateInstaller()
            $installer.Updates = $result.Updates
            $installer.Install()
            
            # 等待安装完成
            while ($installer.Status -ne 5) {
                Start-Sleep -Seconds 10
            }
            
            Write-Host "Updates installed successfully."
        } else {
            Write-Host "No updates available."
        }
    }
}

Write-Host "All servers have been processed."
