"There is a new version of Google Chrome available" notification
When Google Chrome hasn't been used for an extended period of time, you may see a little pop-up appear on your screen, asking whether you want to give the latest version of the browser a try or whether you want to uninstall the browser from your computer. Since Google Chrome updates itself automatically, you'll have a new and improved version of the browser waiting for you to try if you select the first option. If you decide that you'd rather not use Google Chrome, you can uninstall it. We hope you'll tell us why in the survey you'll get as part of the uninstall process.
You won't be prompted again if you click Don't bug me.
