Google Chrome should update automatically as new versions are released and is only installed when Chrome is restarted. You can check for browser updates in the following manner:
- Check the More menu at the top right (marked below in red).
- If the colour is either green, orange, or red, an update is waiting.
- To update, click the More menu.
- Click Update Google Chrome.
- Click Relaunch.
Chrome saves your opened tabs and windows and then reopens them automatically when it restarts. If you prefer not to restart immediately, click Not now. Chrome will apply the updates next time you restart it.
