Powering Up Windows: Create and Run Services Using PowerShell

Creating a Service Manually Using PowerShell

If youre a Windows user, you may already know that services are programs running in the background that perform specific tasks, like updating antivirus definitions or syncing files. Sometimes, you might need to manually create a service to run a background program that performs a specific task.

In this article, well explore how to create a service using PowerShell, a powerful task automation tool.

Example of Creating a Test Service Using PowerShell

To create a service using PowerShell, well need to open PowerShell with administrator privileges. To do this, right-click on the PowerShell icon and select Run as administrator.

Once the PowerShell window is open, type in the following command:

“`

New-Service -Name TestService -BinaryPathName c:tempTestService.exe -DisplayName “Test Service” -Description “This is a test service”

“`

Lets break down this command. New-Service is a PowerShell cmdlet that creates a new service.

The rest of the command sets the parameters for the service:

– -Name TestService sets the name of the service to TestService

– -BinaryPathName c:tempTestService.exe sets the path to the executable file that the service will run

– -DisplayName Test Service sets the display name of the service to Test Service

– -Description This is a test service sets the description of the service to This is a test service

Once you run this command, youll see the message TestService has been successfully created. You can now go to the Services console (Control Panel > Administrative Tools > Services) and look for the Test Service.

You can start, stop, pause, and resume the service from here.

Steps Involved in Creating a Service Using PowerShell

Now that you know how to create a service using PowerShell, lets explore the steps involved in creating a service manually. Step 1: Identify the background program you want to run as a service and create an executable file for it.

You can use any programming language to create the executable file. Step 2: Open PowerShell with administrator privileges and type in the command to create a new service, as seen in the previous example.

Step 3: Check if a service with the same name already exists. To do this, run the command:

“`

Get-Service -Name TestService

“`

If the service already exists, PowerShell will display information about the service. If it doesnt exist, PowerShell will display an error message.

Step 4: If the service already exists, delete it using the command:

“`

Remove-Service -Name TestService

“`

Step 5: Run the command to create a new service, as seen in step 2. Step 6: Start the service using the command:

“`

Start-Service -Name TestService

“`

You can also stop, pause, and resume the service using PowerShell commands.

Code Explanation for Creating a Service Using PowerShell

Lets take a closer look at the PowerShell command used to create a service and understand each parameter. Setting Parameters for the Service Name, Path, Description, and Configuration

The first parameter in the New-Service cmdlet is -Name, which sets the name of the service.

In the example, the name is TestService. You can set any name you want as long as it is unique.

The second parameter is -BinaryPathName, which sets the path to the executable file that the service will run. In the example, the file is located in the c:temp folder and is named TestService.exe.

You can set the path to any executable file you want to run as a service. The third parameter is -DisplayName, which sets the display name of the service.

In the example, the display name is Test Service, which will appear in the Services console. You can set any display name you want.

The fourth parameter is -Description, which sets the description of the service. In the example, the description is This is a test service.

You can set any description you want.

Checking if the Service Already Exists and Deleting It

Before creating a new service, its important to check if a service with the same name already exists. This can be done using the Get-Service cmdlet.

If the service already exists, you can delete it using the Remove-Service cmdlet.

Creating a New Service and Starting It

Once youve set the parameters for the service and checked if the service already exists, you can create a new service using the New-Service cmdlet. You can then start the service using the Start-Service cmdlet.

Conclusion

In this article, we explored how to create a service using PowerShell and the steps involved in creating a service manually. We also took a closer look at the PowerShell command used to create a service and understood each parameter.

By using PowerShell to create a service, you can automate background processes and achieve greater efficiency with your Windows system.

Running the Program and Checking the Service

Now that weve covered how to create a service manually using PowerShell, lets look at how to run the program and check the service to make sure its working as intended.

Executing the Example Code in PowerShell and Getting the Output

To demonstrate how to run a program as a service using PowerShell, well create a simple Hello World program in C#. Open your text editor of choice and type in the following code:

“`

using System;

namespace HelloWorld

{

class Program

{

static void Main(string[] args)

{

Console.WriteLine(“Hello World!”);

}

}

}

“`

Save the file as HelloWorld.cs in the c:temp folder. Next, well compile the file into an executable using the C# compiler.

Open PowerShell with administrator privileges and navigate to the c:temp folder using the command:

“`

cd c:temp

“`

Now, type in the following command to compile the C# file into an executable:

“`

C:WindowsMicrosoft.NETFrameworkv4.0.30319csc.exe /out:HelloWorld.exe HelloWorld.cs

“`

This command tells the C# compiler to output the executable as HelloWorld.exe and the input source file as HelloWorld.cs. You should now see a new file named HelloWorld.exe in the c:temp folder.

Next, well create a service using the New-Service cmdlet in PowerShell. In the PowerShell window, type in the following command:

“`

New-Service -Name HelloWorldService -BinaryPathName C:tempHelloWorld.exe

“`

This command creates a new service named HelloWorldService and sets the path to the HelloWorld.exe file.

To run the program as a service, we need to start the service using the Start-Service cmdlet:

“`

Start-Service -Name HelloWorldService

“`

You should now see the message Hello World! in the PowerShell window. This means the program has executed successfully.

If you dont see the message, there may be an error in your code or your service settings. Checking the Service in the System’s Services Section

To check the service, well use the Services console in Windows.

Open the Services console by going to Control Panel > Administrative Tools > Services. Look for the HelloWorldService in the list.

You can start, stop, pause, and resume the service from this console. If you click on the Properties button, you can also view and change the settings of the service, such as its display name and description.

If you want to delete the service, you can use the Remove-Service cmdlet in PowerShell:

“`

Remove-Service -Name HelloWorldService

“`

This will delete the service and any associated settings.

Conclusion

In this article, we covered how to run a program as a service using PowerShell and checked the service in the Services console. By using PowerShell to create and run services, you can automate background processes and achieve greater efficiency with your Windows system.

Remember to test your code and service settings thoroughly before deploying them in a production environment. In this article, we explored how to create and run services using PowerShell in Windows.

We covered the steps involved in creating and deleting a service manually, set parameters for the service, ran a program as a service, and checked the service in the Services console. By using PowerShell, you can automate background processes, improve system efficiency, and achieve greater control of your environment.

Remember to test your code and service settings thoroughly before deploying them in a production environment. The ability to create and manage services using PowerShell is a valuable skill for any Windows user to have.
