# Hosts Module
## Synopsis
Manages configuration for the Hosts File Editor utility, a quick editor for
the Windows hosts file.
## Description
The `Hosts` module configures PowerToys Hosts File Editor, a utility that
provides a user-friendly interface for viewing and editing the Windows hosts
file. It simplifies the process of adding, modifying, and managing DNS
entries in the hosts file.
## Properties
The Hosts module supports the following configurable properties:
### LaunchAdministrator
Controls whether the Hosts File Editor launches with administrator privileges
by default.
**Type:** boolean
**Default:** `false`
**Description:** When enabled, the editor will always attempt to launch with
elevated permissions, which is required to edit the hosts file.
### LoopbackDuplicates
Controls how duplicate loopback addresses are handled.
**Type:** boolean
**Default:** `false`
### AdditionalLinesPosition
Controls where additional lines are positioned when editing entries.
**Type:** integer
**Allowed values:**
- `0` - Top
- `1` - Bottom
**Default:** `0`
## Examples
### Example 1 - Enable admin launch with direct execution
This example configures the Hosts editor to always launch with admin rights.
```powershell
$config = @{
settings = @{
properties = @{
LaunchAdministrator = $true
}
name = "Hosts"
version = "1.0"
}
} | ConvertTo-Json -Depth 10 -Compress
PowerToys.DSC.exe set --resource 'settings' --module Hosts --input $config
```
### Example 2 - Configure with DSC
This example enables administrator launch and configures line positioning.
```bash
dsc config set --file hosts-config.dsc.yaml
```
```yaml
# hosts-config.dsc.yaml
$schema: https://aka.ms/dsc/schemas/v3/bundled/config/document.json

- name: Configure Hosts File Editor
type: Microsoft.PowerToys/HostsSettings
properties:

LaunchAdministrator: true
AdditionalLinesPosition: 1

```
### Example 3 - Install and configure with WinGet
This example installs PowerToys and configures the Hosts editor for admin
launch.
```bash
winget configure winget-hosts.yaml
```
```yaml
# winget-hosts.yaml
