Google has launched a pop-up advertisement on Google.com promoting Chromebooks, targeting Windows 10 laptop owners as Microsoft ends support for that operating system in October. The ad encourages users to switch to a Chromebook instead of upgrading to Windows 11. It directs users to a "switch to Chromebook" portal showcasing Chromebook Plus models. The promotional video features a generic laptop with elements suggesting its Windows origins, including a 'virus detected' warning and a spinning circle associated with Windows systems. While Chromebooks offer advantages in security and simplicity, the ad implies Windows 11 lacks these features, which is misleading as Windows 11 also has strong security. Users can extend Windows 10 support until October 2026, indicating no immediate need to switch. The Chromebook pop-up may be selectively targeting certain Windows 10 users.
