+
+NETworkManager now supports system-wide policies, giving administrators centralized control over application settings across all users on a machine. This is especially useful in enterprise environments where consistent configuration and security standards need to be enforced.

+
+## What Are System-Wide Policies?
+
+System-wide policies allow administrators to enforce specific application settings for all users on a machine. When a policy is active, the corresponding setting is locked in the UI and displays a shield icon along with a message indicating that the setting is managed by an administrator. Users can see the enforced value but cannot change it.
+
+This ensures that critical settings — such as whether the application checks for updates at startup — remain consistent and tamper-proof across your organization.
+
+## How to Configure Policies
+
+Policies are defined in a simple `config.json` file placed in the same directory as `NETworkManager.exe`.
+
+**File location:**
+
+- **Installed version**: `C:\Program Files\NETworkManager\config.json`
+- **Portable version**: Same directory as `NETworkManager.exe`
+
+**Example `config.json`:**
+
+```json
+{
+  "Update_CheckForUpdatesAtStartup": false
+}
+```
+
+A `config.json.example` file is included in the application directory for reference. Simply rename it to `config.json` and set your desired policy values. Property names follow the pattern `Section_SettingName` — see the [settings documentation](https://borntoberoot.net/NETworkManager/docs/category/settings) for available policy names.
+
+:::note
+
+The file must be named exactly `config.json`, contain valid JSON, and the application must be restarted for changes to take effect.
+
+:::
+
+## Deploying Policies
+
+You can deploy the `config.json` file using your preferred method:
+
+- **Group Policy** — Use Group Policy preferences or a startup script to copy the file to the installation directory.
+- **Configuration management** — Deploy via SCCM/ConfigMgr, Microsoft Intune, Ansible, or similar tools.
+- **Scripts** — Use PowerShell scripts or PSAppDeployToolkit for scripted deployments.
+- **Manual** — Hand-copy the file for small-scale rollouts.
+
+:::warning
+
+Ensure the `config.json` file has appropriate permissions so that regular users cannot modify it. On standard installations in `Program Files`, this is automatically enforced by Windows file permissions.
