Simple Window service

Hi,
Here i want to explain a simple window service which logs the data on text file for every start and stop operations of service.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.IO;
using System.Net.Mail;
using System.Timers;

namespace PracticeService
{
    public partial class Service1 : ServiceBase
    {
        FileStream fs = new FileStream(@"D:\Practive\Servicelogs\CabRequestServicelog.txt", FileMode.OpenOrCreate, FileAccess.Write);
        public Service1()
        {
            InitializeComponent();
        }
        protected override void OnStart(string[] args)
        {
              WriteLog("Cab Request Service started");
        }
        protected override void OnStop()
        {
            WriteLog("Cab Request Service Stopped");

        }
        public void WriteLog(string data)
        {
            StreamWriter m_streamWriter = new StreamWriter(fs);
            m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);
            m_streamWriter.WriteLine(data);
            m_streamWriter.Flush();
            m_streamWriter.Close();
        }
    }
}

So once window service is done using window service template in VSS 2008
no we need to deploy this service using intallutill.exe.
