+#### Running the uninstaller in console mode
+
+Besides running the advanced uninstaller in its user-interactive mode, you can also use command-line arguments to uninstall AdGuard for Windows. To do this, follow the instruction below:
+
+1. Open the Command prompt by typing *cmd* on the start menu.
+2. On the Command prompt, use `/console` to run the uninstaller in console mode, without the interactive UI. All the command-line parameters below will be ignored if the `/console` mode is not activated.
+3. Use `/adblocker` to uninstall AdGuard for Windows.
+4. You can also use `/advanced` to force the uninstaller to run in *Advanced mode*, and `/settings` to force the uninstaller to remove user settings along with the application.
