# Windows Device Installation

### Step 1: Download the Installer

Download the installer [from GitHub](https://github.com/atsign-foundation/noports/releases/download/v5.8.7/NoPortsInstaller-windows-x64.zip). Then unzip the file.

### Step 2: Activate your client Atsign

{% hint style="warning" %}
If you've activated your **client** atSign on another device already, this step will not work. Instead, follow this guide: [Reuse your client atSign on another machine](/installation-faq/reuse-your-client-atsign-on-another-machine.md)
{% endhint %}

## FAQ

### How does the Windows Service work?

We use a lightweight wrapper service to run sshnpd. It pulls the arguments from the Windows Registry and executes sshnpd with them.

### How do I start or stop the service?

Open services.msc (appears as "services" from the start menu). The service will be called `sshnpd` with description `NoPorts-SSH-Daemon` . Click on the service and you will be provided with options to start/restart/stop the service depending on it's current status.

### How do I modify my configuration?

Open the registry editor (a.k.a. regedit) and navigate to `Computer\HKEY_LOCAL_MACHINE\SOFTWARE\NoPorts` . The `DeviceArgs` entry will contain all of the arguments that get passed directly into sshnpd. You may modify these accordingly, then [restart the service](#how-do-i-start-or-stop-the-service).
