    HI ,

    can anyone tell me why (Get-CimInstance -ClassName win32_service)|get-member do not have method called startservice and stopservice? where (Get-WmiObject -Class win32_service)|Get-member have startservice and stopservice.

    As Microsoft is not developing wmiobject anymore is it not feasible to include these method in CimInstance also????

    This is a more challenging topic.  You could say the cim commands are less user friendly than the wmi commands when it comes to methods.  You need to use get-cimclass to list the methods.  Both types of commands are using the same wmi database on the backend.


    get-cimclass win32_service | % cimclassmethods

    And then invoke-cimmethod to invoke a method.  At least the -name parameter supports tab completion.  You can't leave out '-name'.  A returnvalue of 0 is success.


    get-ciminstance win32_service | where name -eq spooler |
      Invoke-CimMethod -name stopservice

    ReturnValue PSComputerName
    ----------- --------------

    You people new to PowerShell and windows technology need to learn to use help before asking questions.
