-## Step 3: Register td-agent to Windows service
+### Step 3: Run td-agent as Windows service
+
+Since version 4.0.0, Td-agent is registered as Windows service
+permanently by msi installer.
+You can start Td-agent service by manually.
+
+#### Using GUI
+
+Please guide yourself to
+`Control Panel -> System and Security -> Administrative Tools -> Services`,
+and you'll see `Fluentd Windows Service` is listed.
+
+Please double click `Fluentd Window Service`, and click `Start` button.
+Then the process will be executed as Windows Service.
+
+#### Using net.exe
+
+```
+> net start fluentdwinsvc
+The Fluentd Windows Service service is starting..
+The Fluentd Windows Service service was started successfully.
+```
+
+#### Using Powershell Cmdlet
+
+```
+PS> Start-Service fluentdwinsvc
+```
+
+Note that using `fluentdwinsvc` is needed to start Fluentd service in commandline.
+Because `fluentdwinsvc` is service name and it should be passed in `net.exe` or `Start-Service` Cmdlet.
+
+The log file will be located at `C:/opt/td-agent/td-agent.log` as we
+specified in Step 3.
+
+
+### Step 4: Install Plugins
+
+Open `Td-agent Command Prompt` and use `fluent-gem` command.
+
+```
+> fluent-gem install fluent-plugin-xyz --version=1.2.3
+```
+
+## Td Agent 3
+
+
+### Step 1: Install td-agent

+
+
+### Step 2: Run td-agent from Command Prompt
+
+First, please prepare your config file located at
+`C:/opt/td-agent/etc/td-agent/td-agent.conf`. The config below is the
+simplest example to output any incoming records to td-agent's log file.
+
+```
+<source>
+  @type forward
+</source>
+<match test.**>
+  @type stdout
+</match>
+```
+
+After you've installed .msi package, you'll see the program called
+`Td-agent Command Prompt` installed. Please double click this icon in
+the Windows menu (below is how it looks like on Windows Server 2012).
+
+![](/images/msi-td-agent-command-prompt.png)
+
+In the prompt, please execute the command below to launch td-agent
+process.
+
+```
+> fluentd -c etc\td-agent\td-agent.conf
+```
+
+Then, please launch another `Td-agent Command Prompt` and type the
+command below. This will send a record to td-agent process.
+
+```
+> echo {"message":"hello"} | fluent-cat test.event
+```
+
+It's working properly if td-agent process outputs the message
+`test.event: {"k", "v"}`.

+
+### Step 3: Register td-agent to Windows service
 
 Next, let's register td-agent to Windows service to permanently run as a
 server process. Please execute `Td-agent Command Prompt` again but with
 administrative privilege, and type the two commands below.
 
-```
-> fluentd --reg-winsvc i
+```                                                                                                                                                > fluentd --reg-winsvc i
