Creating and managing services in Windows can be a daunting task, especially for those who are new to system administration. Fortunately, PowerShell makes it easier to create and run services without needing to delve deep into the graphical user interface.

In this tutorial, we will walk you through the process of creating and running a service using PowerShell. Whether you are automating tasks or managing server applications, knowing how to handle services programmatically can save you time and effort. By the end of this article, you’ll have a solid understanding of how to create and run services in PowerShell, making your administrative tasks smoother and more efficient.

Understanding Windows Services

Before we dive into the practical steps, it’s important to understand what Windows services are. Services are long-running executable applications that run in their own Windows sessions. They can start automatically when the computer boots, can run in the background without user intervention, and can be configured to restart if they fail. PowerShell provides cmdlets that allow you to create, manage, and interact with these services easily.

Creating a Service in PowerShell

To create a service in PowerShell, you typically need a program or executable that the service will run. For the sake of this example, let’s assume you have a simple executable called MyService.exe. Here’s how you can create a service using PowerShell:

New-Service -Name MyService -BinaryPathName "C:\Path\To\MyService.exe" -DisplayName "My Sample Service" -StartupType Automatic

This command creates a new service named “MyService” that points to your executable. The -StartupType Automatic parameter ensures that the service starts automatically when the system boots.

Output:

Service MyService created successfully.

In this command:

• New-Service is the cmdlet used to create a new service.
• -Name specifies the name of the service.
• -BinaryPathName is the path to the executable that the service will run.
• -DisplayName is the name that will appear in the Services management console.
• -StartupType defines how the service starts when the computer boots.

After running this command, your service will be created and can be found in the Services management console. If you need to verify that the service has been created successfully, you can use the Get-Service cmdlet:

Get-Service -Name MyService

Output:

Status   Name               DisplayName
------   ----               -----------
Stopped  MyService          My Sample Service

The Get-Service command retrieves the status of the newly created service, confirming that it exists and is currently stopped.

Running the Service

Once you’ve created the service, the next step is to start it. To do this, you can use the Start-Service cmdlet. Here’s how to run your newly created service:

Start-Service -Name MyService

Output:

Service MyService started successfully.

The Start-Service cmdlet initiates the service you created. If you check the status again using the Get-Service cmdlet, you should see that the service is now running.

Get-Service -Name MyService

Output:

Status   Name               DisplayName
------   ----               -----------
Running  MyService          My Sample Service

In this example:

• Start-Service is the cmdlet that starts the specified service.
• After executing this command, the service transitions from a stopped state to a running state.

Stopping and Removing the Service

When you no longer need the service, you can stop and remove it using the following commands:

To stop the service, you would use:

Stop-Service -Name MyService

Output:

Service MyService stopped successfully.

To remove the service entirely, the command is:

Remove-Service -Name MyService

Output:

Service MyService removed successfully.

The Stop-Service cmdlet halts the operation of the service, while Remove-Service deletes it from the system entirely. This is useful for cleaning up after testing or when a service is no longer needed.

Conclusion

Creating and managing services in PowerShell is a powerful way to automate and streamline administrative tasks. With just a few commands, you can create, start, stop, and remove services, allowing you to maintain better control over your system processes. This tutorial has provided you with the foundational knowledge to work with services in PowerShell, making it easier for you to manage your Windows environment effectively. Whether you are a seasoned admin or a beginner, mastering these commands will undoubtedly enhance your productivity.

Understanding Services in Windows

What are Windows Services?

Windows services are specialized applications that run in the background, allowing various tasks to continue without user intervention. They are primarily designed to facilitate system functions, automatically starting at boot time or on demand. Unlike traditional applications, services can operate without a direct user interface, enabling them to run even when no user is logged into the system.

Common examples of Windows services include the Windows Update Service, which manages system updates, and the Print Spooler, responsible for handling print jobs.

Why Use PowerShell for Service Management?

PowerShell provides a powerful framework for managing Windows services efficiently. The use of scripts allows for automation, reducing the manual labor involved with repetitive service management tasks. This increases consistency across operations and minimizes the risk of human error. With PowerShell’s robust command structure, IT professionals can automate complex service workflows, leading to more efficient systems management.

Mastering PowerShell Get Service: Quick Tips and Tricks

Getting Started with New-Service in PowerShell

Syntax of the New-Service Command

The `New-Service` command in PowerShell enables the creation of a new Windows service directly through the command line. Its basic syntax consists of the command followed by a series of parameters that define the service’s characteristics. Understanding how to use these parameters is critical for effective service management.

New-Service -Name "<ServiceName>" -BinaryPathName "<PathToExecutable>" [-DisplayName "<DisplayName>"] [-Description "<Description>"] [-StartupType <StartupType>]

Basic Example of Creating a New Service

Creating a new service involves providing essential parameters that define its identity and behavior. Here’s a straightforward example:

New-Service -Name "MyService" -BinaryPathName "C:\PathToYourExecutable.exe"

In this example:

• -Name specifies the identifier for the service.
• -BinaryPathName indicates where the executable that runs the service is located.

This command sets up a basic service, but adding more characteristics can enhance its utility further.

PowerShell Set Service: A Quick Guide to Service Management

Key Parameters of New-Service

Mandatory Parameters

• -Name: This parameter is crucial as it defines the service’s unique name. It’s important to follow Windows naming conventions since choosing an existing service name will lead to errors.

• -BinaryPathName: It specifies the exact path to the executable that the service will run. This must be accurate; otherwise, the service will fail to start.

Optional Parameters

• -DisplayName: This is the user-friendly name displayed in service manager interfaces. It can be different from the service name for clarity.

• -Description: A succinct summary of what the service does. This is helpful for documentation and for those who might manage the service in the future.

• -StartupType: This parameter dictates when the service should start. Options include:

  • Automatic: The service starts when the computer boots.
  • Manual: The service only starts when explicitly invoked by a user or application.
  • Disabled: The service cannot be started; useful for services that are not needed.

Using `-DependentServices` and Other Advanced Parameters

Setting dependencies can create structured relationships between services. For example, if one service relies on another to function correctly, configuring this can preemptively manage startup sequences:

New-Service -Name "MyDependentService" -BinaryPathName "C:\MyDependentService.exe" -DependentServices "MyService"

Here, «MyDependentService» will not start until «MyService» is up and running.

PowerShell может  управлять службами Windows. Создать новую службу можно с помощью командлета New-Service. Создадим такой же сервис, как и в предыдущем примере, только добавим к нему описание (Description):

New-Service -Name MyService -BinaryPathName C:\MyService\MyService.exe`
-DisplayName ″My New Service″ -Description ″Very Important Service !!!″

Изменить параметры службы можно командлетом Set-Service:

Set-Service -Name MyService -Description ″Not Very Important Service″ -StartupType Manual

Картинка с сайта: www.itworkroom.com

PowerShell имеет примерно такой же функционал как и Sc.exe, разве что позволяет добавить описание. А вот для удаления служб в PS простого способа нет, придется воспользоваться вот такой конструкцией:
(Get-WmiObject win32_service -Filter ″name=′MyService′″).delete()
