## Windows service support

Windows services are long-running background processes, similar to Unix daemons.
You can run Core Agent as a Windows service.

### Register Core Agent as a service

For example, given the following installation layout:

```shell theme={null}
C:\calyptia-fluent-bit\
├── conf
│   ├── calyptia-fluent-bit.conf
│   └── parsers.conf
│   └── plugins.conf
└── bin
    ├── calyptia-fluent-bit.dll
    └── calyptia-fluent-bit.exe
    └── calyptia-fluent-bit.pdb
```

You can register Core Agent as a Windows service by running the following command:

```shell theme={null}
% sc.exe create fluent-bit binpath= "C:\Program Files\calyptia-fluent-bit\bin\calyptia-fluent-bit.exe -c C:\Program Files\calyptia-fluent-bit\conf\calyptia-fluent-bit.conf"
```

### Start the Core Agent service

To start the Core Agent service, run the following command:

```shell theme={null}
% sc.exe start calyptia-fluent-bit
```

### Auto-start the Core Agent service

To configure the Core Agent service to automatically start on boot, run the
following command:

```shell theme={null}
% sc.exe config calyptia-fluent-bit start= auto
```

### Stop the Core Agent service

To stop the Core Agent service, run the following command:

```shell theme={null}
% sc.exe stop calyptia-fluent-bit
```
