### Big picture

Start, stop, and update {{site.prodnameWindows}} services on the Linux master node, and uninstall for {{site.prodnameWindows}}.

### How to

#### Start and stop {{site.prodnameWindows}} services

- Install and boot {{site.prodnameWindows}}: `install-calico.ps1`
- Start {{site.prodnameWindows}} services:`start-calico.ps1`
- Stop {{site.prodnameWindows}} services: `stop-calico.ps1`

#### Update {{site.prodname}} services

To change the parameters defined in `config.ps1`:

- Run `uninstall-calico.ps1` to remove {{site.prodnameWindows}} service configuration
- Modify the configuration
- Run `install-calico.ps1`to reinstall {{site.prodnameWindows}}.

Because `config.ps1` is imported by the various component startup scripts, additional environment variables can be added, as documented in the [{{site.prodname}} reference guide]({{site.baseurl}}/reference).

#### Update service wrapper configuration

The `nssm` command supports changing a number of configuration options for the {{site.prodname}} services. For example, to adjust the maximum size of the Felix log file before it is rotated:

```
PS C:\... > nssm set TigeraFelix AppRotateBytes 1048576
```

#### Uninstall {{site.prodnameWindows}} from Windows nodes

The following steps removes {{site.prodnameWindows}} (for example to change configuration), but keeps the cluster running.

1. Remove all pods from the Windows nodes.
1. On each Windows node, run the uninstall script:

   ```
   PS C:\CalicoWindows > .\uninstall-calico.ps1
   ```
   >**Note**: If you are uninstalling to change configuration, make sure that you run the uninstall script with the old configuration file.
