# openHAB on Windows
The following instructions will guide you through the process of setting up openHAB.
This page is structured as follows:
{::options toc_levels="2..4"/}
- TOC
{:toc}
## Prerequisites
First, be sure to check that your system has the necessary [prerequisites]({{base}}/installation/index.html#prerequisites).
Add the `JAVA_HOME` System Environment Variable in Windows.
Navigate to:
- Control Panel ➡️ System and Security ➡️ System ➡️ Advanced System Settings ➡️ Environment Variables ➡️ System Variables
Create a New System Variable based on your Java installation directory:
![JAVA_HOME](images/JAVA_HOME.png)
The directory that openHAB is installed to must **contain no spaces**.
On this page, we will be using `C:\openHAB` as an example.
## Installation
The openHAB runtime is distributed using a platform-independent zip file.
To install it, follow these simple steps:
1. Download the latest Windows Stable or Snapshot ZIP archive file for manual installation from the [Download](https://www.openhab.org/download/) page.
2. Unzip the file in your chosen directory (e.g. `C:\openHAB`)
3. Start the server: Launch the runtime by executing the script `C:\openHAB\start.bat` and wait a while for it to start and complete.

4. Point your browser to `http://localhost:8080`.
You should now follow the first installation procedure.
### File Locations
Assuming a successful install, you will now have various folders inside `C:\openHAB`:
| | Windows Installation |
|:--------------------------------:|:-----------------------------|
| openHAB application | `C:\openHAB\runtime` |
| Additional add-on files | `C:\openHAB\addons` |
| Site configuration | `C:\openHAB\conf` |
| Log files | `C:\openHAB\userdata\logs` |
| Userdata like rrd4j databases | `C:\openHAB\userdata` |
| Service configuration | `C:\openHAB\userdata\etc` |
## Backup
Make sure that you make regular backups of the **conf** and **userdata** folders, you can zip and unzip these folders too and from openHAB installations (even across most versions).
When you have a setup that you are happy with, it would be a good idea to make a backup of the whole `C:\openHAB` folder.
Which can be used any time after a failure.
## Updating the openHAB Runtime
To start the update process, run PowerShell as an administrator and use the following commands, while replacing `x.x.x` with the wanted openHAB version.
Assuming you have openHAB installed in `C:\openHAB`:
```shell
cd C:\openHAB
. .\runtime\bin\update.ps1
Update-openHAB -OHVersion x.x.x
```
Now that openHAB has updated, you only need to run the above commands again for future versions.
## Starting openHAB as a Service
By installing the openHAB process as a service in Windows, you can:
- Launch it automatically upon system startup
- Run it in the background
**Windows Service Installation Steps**
1. Complete the [prerequisites](#prerequisites) and regular [installation](#installation) steps, including the package selection
2. Issue the following two commands in your openHAB console:
```shell
feature:install service-wrapper
wrapper:install --name "openHAB" --display "openHAB" --description "openHAB Service"
```

3. Shutdown the openHAB instance by typing `logout` in the currently running console.
4. Update the newly created `C:\openHAB\userdata\etc\openHAB-wrapper.conf` to include all necessary parameters.
- Copy all the config text from the below section and paste it in your `openHAB-wrapper.conf`, replacing all existing content.
- Adapt the first entry (`OPENHAB_HOME`) to match your openHAB installation directory.
```conf

5. Open an elevated command prompt and type the following commands:

C:\openHAB\userdata\bin\openHAB-service.bat install
net start "openHAB"
```

6. Your openHAB Windows service is now installed and running.
Validate proper operations by:
- Browsing to [http://localhost:8080](http://localhost:8080)
- Verifying that the Windows Service is running and set to Automatic Startup type.
Use `services.msc` and find the `openHAB` service.

- Logging in with an SSH client to the console (see info below)
### Connecting to the openHAB console
You can connect to openHAB's console using the the `C:\openHAB\runtime\bin\client.bat` script on the local machine.
Alternatively, you can use a standard SSH client:
- Install an SSH client application, e.g., [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html), [KiTTY](http://kitty.9bis.net/) or [Xshell 5](https://www.netsarang.com/products/xsh_overview.html)
- Setup a session with the following parameters:
- Host: 127.0.0.1
- Port: 8101
- Username: `openhab`
- Password: `habopen`
