On April 8, 2014, Microsoft stopped supporting Windows XP. This isn’t just a formality: computers running Windows XP haven’t received security patches in over a year and are facing a number of critical security vulnerabilities. At the operating system level, computers running XP are inherently in danger of being infected by malware and viruses, making it increasingly difficult for Chrome to provide a secure browsing environment. That’s why we strongly encourage everyone to update to a supported, secure operating system.
That said, we know that not everyone can easily switch to a newer operating system. Millions of people are still working on XP computers every day. We want those people to have the option to use a browser that’s up-to-date and as safe as possible on an unsupported operating system. We previously announced that we’d keep supporting Chrome on Windows XP through ‘at least’ April 2015. It’s April 2015 now, and we’re extending that commitment. We will continue to provide regular updates and security patches to Chrome on XP through the end of 2015.
