尝试更新Windows功能时;当我将UseShellExecute更新为“true”时;“Process对象必须将UseShellExecute属性设置为false才能重定向IO流。”我收到错误。当我将其设置为False时;无法更新，该怎么做？您还有其他建议吗？

                var dism = new Process();
                dism.StartInfo.WorkingDirectory = systemPath;
                dism.StartInfo.Arguments = arguments;
                dism.StartInfo.FileName = "dism.exe";
                dism.StartInfo.Verb = "runas";

                dism.StartInfo.UseShellExecute = true;
                dism.StartInfo.RedirectStandardOutput = true;
                dism.Start();
                var result = dism.StandardOutput.ReadToEnd();
                dism.WaitForExit();
            }
            catch (Exception ex)
            {
            }

        }`

我尝试使用dism.exe和cmd.exe更新该功能，当它出现授权错误时，我使用了Verb属性'

由于使用.Verb = "RunAs"需要.UseShellExecute = true，并且由于后者不能与RedirectStandardOutput = true组合，因此您不能 * 直接 * 在内存中捕获提升的进程的输出。
看起来系统本身，通过考虑安全性的设计，阻止了非提升进程直接捕获提升进程的输出。
*解决方法是通过 *shell间接 * 启动目标可执行文件（在您的情况下是dism.exe），然后使用后者的重定向功能（>）**将目标可执行文件的输出（总是）捕获到 * 文件 * 中，如下所示。

string systemPath = Path.Combine(Environment.ExpandEnvironmentVariables("%windir%"), "system32");

// Create a temp. file to capture the elevated process' output in.
string tempOutFile = Path.GetTempFileName();

var dism = new Process();
dism.StartInfo.WorkingDirectory = systemPath;
// Use cmd.exe as the executable, and pass it a command line via /c
dism.StartInfo.FileName = "cmd.exe" ;
// Use a ">" redirection to capture the elevated process' output.
// Use "2> ..." to also capture *stderr* output.
// Append "2>&1" to capture *both* stdout and stderr in the file targeted with ">"
dism.StartInfo.Arguments = 
  String.Format(
    "/c {0} {1} > \"{2}\"", 
    "dism.exe", arguments, tempOutFile
  );
dism.StartInfo.Verb = "RunAs";
dism.StartInfo.UseShellExecute = true;

dism.Start();
dism.WaitForExit();
// Read the temp. file in which the output was captured...
var result = File.ReadAllText(tempOutFile);
// ... and delete it.
File.Delete(tempOutFile);

首先，你可以使用WindowsPrincipal::IsInRole()来检查你是否在高架运行，详细信息见Microsoft Learn。
其次，这可能是使用原生PS比cmdlet方法更容易的情况之一（诚然，仍然不是很好）。
如果脚本应在客户机和服务器操作系统上运行：使用Get-WmiObject或Get-CimInstance获取对您正在运行的对象的引用。ActiveDirectory也具有该信息（在operatingSystem属性中）。
对于服务器，请使用ServerManager模块中的Get-WindowsFeature。对于客户端，请使用DISM模块中带开关-Online的Get-WindowsOptionalFeature，如果确实需要支持6.3.xxxx之前的操作系统，则可以从具有该开关的计算机复制该开关，并将其添加到$Env:Path之前的C：\Windows和C：\Windows\System32。
对于任一平台，只需传递要配置的特性列表。
如果在一个（二进制）cmdlet中，你必须调用外部工具，那么它们的优势就大部分消失了。也许可以使用托管API访问Windows CBS来避免这种情况，但即使这样，基于脚本的方法也会更快地获得更多结果，特别是因为你可以在dism.exe周围快速打包。
