Powershell 显示所有已停止的自动服务并尝试启动这些服务

Question

I want to create a PS script where it will display all the automatic services that are stopped, and will attempt to start the services afterward.

Below is the PS code. It is successfully displayed all the stopped services on remote server.

Get-WmiObject Win32_Service -ComputerName SERVER1, SERVER2 |`
where     {($_.startmode -like "*auto*") -and `
        ($_.state -notlike "*running*") -and `
        ($_.name -notlike "gupdate") -and `
        ($_.name -notlike "remoteregistry") -and `
        ($_.name -notlike "sppsvc") -and `
        ($_.name -notlike "lltdsvc") -and `
        ($_.name -notlike "KDService") -and `
        ($_.name -notlike "wuauserv")
        }|`

        select DisplayName,Name,StartMode,State,PSComputerName|ft -AutoSize

Answer 1

You can simply store the results of your query into a variable instead of selecting and displaying it, and you'd have a bunch of win32_Service instances that all have a StartService() method. It's generally a good idea to check the docs of the wmi classes you're using, most of them have methods that act on the object being represented, instead of having to pipe them around to other cmdlets like most Powershell objects:

Win32_Service class methods

You'd use it like this:

    $services = Get-WmiObject Win32_Service -ComputerName SERVER1, SERVER2 |`
    where     {($_.startmode -like "*auto*") -and `
    # [...]
    }

    $service | select DisplayName,Name,StartMode,State,PSComputerName|ft -AutoSize
    $Service | ForEach {$_.StartService()}

Consider also using Get-Service unless you have a requirement for using WMI. You have a couple differences but the idea is the same:

    $Services = Get-Service -ComputerName SERVER1,SERVER2 |`
    where     {($_.StartType -eq "Automatic") -and `
    ($_.Status -notlike "*running*") -and `
    ($_.Name -notlike "gupdate") -and `
    # ...
    }
    $Services | select Description,Name,StartType,Status,MachineName |ft -AutoSize
    $Services | Start-Service

Also, you could also simplify your filter a lot by using the -notin operator:

    where     {($_.startmode -like "*auto*") -and `
    ($_.state -notlike "*running*") -and `
    ($_.name -notin "gupdate","remoteregistry","sppsvc","lltdsvc","KDService","wuauserv")
    }
