How to find which version of Google Chrome
you have and update it.
4. Click "About Google Chrome."
The version of your Google Chrome browser will appear on the next window, toward the top of the screen.
Going through this process will also prompt the browser to check if there are any updates available. If there are, you will be given the option to relaunch the browser to install those updates.
You can also choose to automatically keep the browser up to date by selecting "Automatically update Chrome for all users," which will require you to enter your computer's password to set up.
