# Residential Proxies - OS Targeting

Residential proxies support operating system (OS), which let you request proxy exits associated with a specific device operating system.

### How to Target an Operating System

To target a specific operating system, add the corresponding `-os-` parameter to your proxy username.

| Operating system | Parameter     | Example           |
| ---------------- | ------------- | ----------------- |
| Windows          | `-os-windows` | `user-os-windows` |
| Android          | `-os-android` | `user-os-android` |
| iOS              | `-os-ios`     | `user-os-ios`     |
| macOS            | `-os-macos`   | `user-os-macos`   |
| Linux            | `-os-linux`   | `user-os-linux`   |

For example, to request a Windows exit:

```text Username theme={null}
user-os-windows
```

### Combining OS Targeting with Other Parameters

OS targeting can be combined with other Regular Residential parameters, including country targeting and sticky sessions.

| Example                                                     | Result                                                            |
| ----------------------------------------------------------- | ----------------------------------------------------------------- |
| `user-country-us-os-windows`                                | Windows exit in the United States                                 |
| `user-country-us-os-windows-session-1235469420-lifetime-15` | Windows exit in the United States with a 15-minute sticky session |

<Note>
  Replace `user` with your own proxy username in all examples.
