Description

Provides a mechanism to start and stop a Windows process.

Parameters

• [String] Path (Key): The executable file of the process. This can be defined as either the full path to the file or as the name of the file if it is accessible through the environment path. Relative paths are not supported.
• [String] Arguments (Key): A single string containing all the arguments to pass to the process. Pass in an empty string if no arguments are needed.
• [PSCredential] Credential (Write): The credential of the user account to run the process under. If this user is from the local system, the StandardOutputPath, StandardInputPath, and WorkingDirectory parameters cannot be provided at the same time.
• [String] Ensure (Write): Specifies whether or not the process should be running. To start the process, specify this property as Present. To stop the process, specify this property as Absent. { Present | Absent }.
• [String] StandardOutputPath (Write): The file path to which to write the standard output from the process. Any existing file at this file path will be overwritten. This property cannot be specified at the same time as Credential when running the process as a local user.
• [String] StandardErrorPath (Write): The file path to which to write the standard error output from the process. Any existing file at this file path will be overwritten.
• [String] StandardInputPath (Write): The file path from which to receive standard input for the process. This property cannot be specified at the same time as Credential when running the process as a local user.
• [String] WorkingDirectory (Write): The file path to the working directory under which to run the process. This property cannot be specified at the same time as Credential when running the process as a local user.

Example 1

#Requires -Module xPSDesiredStateConfiguration

<#
    .DESCRIPTION
        Configuration that starts a process that is provided in the given file
        path with the specified arguments.

    .PARAMETER FilePath
        The path to the executable file to start.

    .PARAMETER Argument
        The arguments for the process to start. Defaults to no argument.

    .EXAMPLE
        xWindowsProcess_StartProcess_Config -FilePath 'C:\WINDOWS\system32\PING.EXE' -Argument '-t localhost'

        Compiles a configuration that starts a process that continuously ping
        localhost, and monitors that the process 'ping' is always started.

#Requires -Module xPSDesiredStateConfiguration

<#
    .DESCRIPTION
        Configuration that starts a process under the given credential, that is
        provided in the given file path with the specified arguments.

    .PARAMETER FilePath
        The path to the executable file to start.

    .PARAMETER Argument
        The arguments for the process to start. Defaults to no argument.

Example 3

#Requires -Module xPSDesiredStateConfiguration

<#
    .DESCRIPTION
        Configuration that stops the process that is provided in the given file
        path, where the argument matches, and if the process is running.

    .PARAMETER FilePath
        The path to the executable file to (process) to stop.

    .PARAMETER Argument
        The arguments for the process to stop. Defaults to no argument.

    .NOTES
        The FilePath could be set to just the process name only if the number of
        returned processed is less than or equal to 8. If more than 8 processes
        are returned, another filter is used to optimize performance, and that
        filter needs the full path to the executable file.

    .EXAMPLE
        xWindowsProcess_StopProcess_Config -FilePath 'C:\WINDOWS\system32\PING.EXE' -Argument '-t localhost'

        Compiles a configuration that stops a 'ping' process if the process exist.
