For other tasks, consider using the LocalService account, which acts as a non-privileged user on the local computer and presents anonymous credentials to any remote server.

Before you decide to add startup parameters, consider whether it's the best way to pass information to your service.
Although they're easy to use and parse, and a user can easily override them, they might be harder for a user to discover and use without documentation.
Generally, if your service requires more than just a few startup parameters, you should use the registry or a configuration file instead. A Windows service can accept command-line arguments, or startup parameters. When you add code to process startup parameters, a user can start your service with their own custom startup parameters in the service properties window. However, these startup parameters aren't persisted the next time the service starts.
To set startup parameters permanently, set them in the registry. Under each service's subkey, use the Parameters subkey to store information that your service can access. You can use application configuration files for a Windows service the same way you do for other types of programs. For sample code, see ConfigurationManager. Select Program. In the Main method, change the code to add an input parameter and pass it to the service constructor:. In MyNewService. This code sets the event source and log name according to the startup parameters that the user supplies.
If no arguments are supplied, it uses default values. To specify the command-line arguments, add the following code to the ProjectInstaller class in ProjectInstaller. Typically, this value contains the full path to the executable for the Windows service. For the service to start up correctly, the user must supply quotation marks for the path and each individual parameter. A user can change the parameters in the ImagePath registry entry to change the startup parameters for the Windows service.
However, a better way is to change the value programmatically and expose the functionality in a user-friendly way, such as by using a management or configuration utility. Program , or Sub Main for Visual Basic projects. Now that you've built the Windows service, you can install it. To install a Windows service, you must have administrator credentials on the computer where it's installed. If the system can't find installutil. This tool is installed with the. If the installutil.
By default, the log is in the same folder as the service executable. The installation can fail if:.

In Windows, open the Event Viewer desktop app. Locate the listing for MyNewLog or MyLogFile1 if you followed the procedure to add command-line arguments and expand it.
You should see the entries for the two actions start and stop that your service performed. In the Developer Command Prompt for Visual Studio window, navigate to the folder that contains your project's output. If the service uninstalls successfully, the command reports that your service was successfully removed.
Create a standalone setup program for others to use to install your Windows service. Inorder to install we have to type installutil -i WindowsService1. Now after successful installation you will recieve an message stating that " The Transacted install has completed ". Now start the service. As per our coding after starting the service we create 2 text documents in the D: drive as per my example.
Those are ContinousLoop. If you could observe i commented a line with while true in Service1. If we uncomment it, the line "Visit DotNetFunda Regularly" prints continuosly untill and unless we explicitly stop the service. The final text documents will look like this. By this way we can create a Windows Service and can work with it accordingly.
