Powershell 4 Get-ScheduledTask 和 Windows [英] Powershell 4 Get-ScheduledTask and Windows

问题描述

我认为无论您使用什么操作系统，如果您安装了 Powershell，您都可以访问相同的默认 cmdlet.

I thought no matter what OS you had, if you had Powershell installed, you would have access to the same default cmdlets.

所以我想在我的 Windows 上使用 Get-ScheduledTask7 机.我安装了 Powershell 4.但是，当我运行它时，出现错误:

So I want to use Get-ScheduledTask on my Windows 7 machine. I have Powershell 4 installed. However, when I run it, I get the error:

Get-ScheduledTask : The term 'Get-ScheduledTask' is not recognized as the name 
of a cmdlet, function, script file, or operable program. Check the spelling of 
the name, or if a path was included, verify that the path is correct and try again.

+ Get-ScheduledTask
+ ~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Get-ScheduledTask:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

如果我在我的 Windows 8.1 上运行 Powershell 4 已经与操作系统一起预装，它可以工作.

If I run on my Windows 8.1 with Powershell 4 already pre-installed along with the OS, it works.

我可以在我的 Windows 7 机器上获取 cmdlet 吗?Microsoft Get-ScheduledTask 页面上没有关于 Windows 7 的任何内容，所以我猜不是.

Can I get the cmdlets on my Windows 7 machine? There is nothing on the Microsoft Get-ScheduledTask page about Windows 7 so I am guessing not.

如果不是，那会不会是使用命令行的情况:

If not then would it be a case of using the command line:

预定任务命令行

毫无疑问有人会指向我这个问题 但那是针对 Powershell 2 的.我使用的是 Powershell 4.

No doubt someone will point me at this question but that was for Powershell 2. I am on Powershell 4.

现在我非常喜欢不重新发明轮子，但是这个 伙计们 看起来是个不错的选择.

Now I am a big fan of not reinventing the wheel, but this guys scripts look a good alternative.

推荐答案

Get-ScheduledTask 依赖于 Windows 7 没有的操作系​​统的底层功能，因此无法运行该操作系统上的 cmdlet，即使使用 PowerShell v4.在您的情况下，您可以利用 schtasks.exe 或 Schedule.Service COM 对象.

Get-ScheduledTask relies on underlying features of the OS that Windows 7 doesn't have, so there is no way to run the cmdlet on that OS, even with PowerShell v4. In your case, you can either leverage schtasks.exe or the Schedule.Service COM object.

您链接的这个答案给出了这些方法的最佳概述，但为了完整起见，我将在此处链接相关资源:

This answer that you linked gives the best overview of these methods, but in the interests of completeness, I'll link the relevant resources here:

schtasks.exe

MS PowerShellPack TaskScheduler 模块 ->(利用Schedule.Service COM 对象)
