# OS Service (exe)

> Install AgentOS as a Windows system service for enterprise and CI/CD.

<Note>
  AgentOS is proprietary software, **free for non-commercial use**. For commercial deployments, a license is required. See [pricing](https://www.askui.com/enterprise) for details.
</Note>

## Prerequisites

* **Windows** (Windows 10, Windows 11, Windows Server 2019+) — see [System Requirements](/06-agent-os/reference/system-requirements) for supported versions.
* **Administrator rights**

<Note>
  To automate the login/lock screen (Secure Attention Sequence), a Group Policy setting must be enabled. See [Troubleshooting](/06-agent-os/how-to-guides/troubleshooting#agent-cant-press-ctrlaltdel) for details.
</Note>

## Installation

<Steps>
  <Step title="Download the installer">
    * [AMD64 (x86\_64)](https://files.askui.com/releases/Installer/Latest/AskUI-Agent-OS-Latest-Service-Installer-Win-AMD64.exe)
    * [ARM64](https://files.askui.com/releases/Installer/Latest/AskUI-Agent-OS-Latest-Service-Installer-Win-ARM64.exe)
  </Step>

  <Step title="Run the installer">
    Run the EXE and approve the administrator elevation request.
  </Step>

  <Step title="Configure the service (optional)">
    The installer includes a **Service Configuration** screen:

    * **Connection Scope:** Use **Public (0.0.0.0)** if AgentOS needs to be reachable from another machine (e.g. a remote CI runner). Keep **Private (127.0.0.1)** for local use only.
    * **Log Level:** `Info` for production, `Debug` for troubleshooting.
    * **Allow CTRL+ALT+DEL:** Enable to automate the Windows lock/login screen (requires Group Policy — see [Troubleshooting](/06-agent-os/how-to-guides/troubleshooting#agent-cant-press-ctrlaltdel)).
    * **Allow control of administrative applications:** Enable only if you need to automate apps running as administrator.

    Click **Next**, then **Install**.
  </Step>

  <Step title="Reboot if prompted">
    If the installer asks to reboot, restart the machine so all changes take effect.
  </Step>
</Steps>

The AskUI Python SDK automatically detects the service and uses it instead of standalone mode. For silent/unattended installation, see [Silent (exe)](/06-agent-os/installation/silent).

## Uninstalling

Always uninstall via **Windows Add/Remove Programs**. Do not remove the service from Windows Services manually.
