Updating Chrome Web Browser
Unless you have specifically disabled it Chrome will check for updates every couple of hours and automatically update itself, but here's how to manually tell Chrome to update itself.
Click the "Customize and Control" button
Click on the "Customize" menu In the top-right corner of the Chrome window. It looks like three little black dots on top of each other.
Click on the "Help" menu item
Click "About Google Chrome"
Chrome will automatically check for updates
As soon as you open the "About" screen for Chrome, it will automatically start to check if there are any updates available for your copy of Chrome. If there are updates available it will start to download them. You don't need to do anything to start this process.
Chrome tells you that it's "Checking for updates..." while it checks for a newer version.
If Chrome finds updates, click "Relaunch" to install them
If Chrome finds updates, it will automatically download and install them. Once this is done you need to click the Relaunch button to finish this process. Clicking it will restart Chrome. Chrome should remember which websites you have open and reopen them when it starts up again.
When Chrome relaunches, you'll have the latest version
Chrome now tells you "Google Chrome is up to date".
Congratulations, you have now ensured that your copy of Chrome is up to date!
