Google has announced they will no longer provide updates for their Chrome browser running on Windows XP, Windows Vista or older versions of Mac OS X after April 2016. This is not unexpected, but it means that people still using those operating systems after that time will further increase the possibility of being infected by malware though running an unsupported operating system AND an unsupported browser.
Today, we’re announcing the end of Chrome’s support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes.
Almost 15% of current Windows users are still running XP or Vista, and even though they are stuck with the "old and busted" Internet Explorer version 8, they could still install and use Google Chrome or Mozilla Firefox as an alternative browser. That at least would allow them to use the Internet with a more modern and more secure web browser.
With Google dropping support for Chrome, these folks will need to turn to Firefox in order to still have a reasonably secure way to browse online.
