After Microsoft stops supporting XP, Google has promised to provide Chrome updates until 2015.

"We recognize that hundreds of millions of users, including a good chunk of current Chrome users, still rely on XP," said Mark Larson, superintendent of public safety (yes, really) at Google Chrome in a blog post.

"Moreover, many organizations still run dozens or even hundreds of applications on XP and may have trouble migrating. Our goal is to support Chrome for XP users during this transition process. Most importantly, Chrome on XP will still be automatically updated with the latest security fixes to protect against malware and phishing attacks."

In an emailed statement, Microsoft said:"Third parties may provide ongoing support for their applications, but it’s important to recognize that support will not address fixes and security patches in the core Windows kernel so new vulnerabilities can still be exploited even though applications might be updated."
