powershell - 如何从 powershell 启动一个进程而不把它带到前面？

Question

我正在为工作编写一个简单的清理脚本，其中应该包括 gpupdate。我想要做的是运行 gpupdate 并捕获输出或在另一个窗口中运行它并将当前窗口保持在顶部。我尝试了多种不同的方式来运行 gpupdate.exe（包括使用具有不同焦点选项的 WSH），但它总是在当前 PowerShell 窗口的前面弹出。PS commandlet Invoke-GPUpdate 显示错误“访问被拒绝”，因此这似乎不是一个可用的解决方案。我目前正在尝试调用 ProcessGPUpdate API，但我的代码一定有问题。无论如何，我真的不喜欢这个解决方案，因为它看起来不会提供反馈/进展。

参考 API：https ://docs.microsoft.com/en-us/previous-versions/windows/desktop/wmi_v2/class-library/remotegpupdate-processgpupdate-method-string-boolean-boolean-boolean-boolean-uint32-string -microsoft-grouppolicy

我当前的非工作代码

Add-Type '@
using Microsoft.GroupPolicy;
public static void ProcessGPUpdate(
string Computer,
bool force,
bool boot,
bool logoff,
bool sync,
uint delayInMinutes,
string target
)
'@

我愿意接受有关如何完成此任务的建议。目前，我正在考虑最小化运行 gpupdate。

编辑：根据要求添加命令输出
