如何在PowerShell中启动和停止进程? [英] How to start and stop processes in PowerShell?

问题描述

这在早于3的PowerShell中应该可以正常工作.我需要运行两个进程:wuapp.exe和desk.cpl(带有ScreenSaver的选项卡).我遇到的问题是，一旦启动wuapp.exe，进程名称就会在任务管理器中显示为explorer.exe-当前代码适用于wuapp.exe，但并非在每台计算机上都有效.另一件事是，当我杀死rundll32时，其他应用程序也将关闭.你有什么建议?

This should work fine in PowerShell older than 3. I need to run two processes: wuapp.exe and desk.cpl with ScreenSaver's tab. The problem I have is that once I start wuapp.exe the process name shows up in Task Manager as explorer.exe - the current code works for wuapp.exe but not on every machine. The other thing is when I kill rundll32 other apps will close also. What do you suggest?

$wshell = New-Object -ComObject Wscript.Shell
Start-Process  wuapp.exe
(New-Object -comObject Shell.Application).Windows() | foreach-object {$_.quit()}
Start-Process rundll32 desk.cpl,InstallScreenSaver
Stop-Process -ProcessName rundll32* -Force

推荐答案

我不完全确定wuapp.exe显示为explorer.exe的意思，但是跟踪rundll32的过程非常简单.

I'm not entirely sure what you mean by wuapp.exe showing up as explorer.exe, but keeping track of the rundll32 process is fairly straightforward.

将Start-Process与PassThru参数一起使用，以使其返回其创建的过程:

Use Start-Process with the PassThru parameter to have it return the process it creates:

$ScreenSaverCpl = Start-Process rundll32 desk.cpl,InstallScreenSaver -PassThru
# Call Stop-Process when no longer needed:
Stop-Process $ScreenSaverCpl
