“For customers running on an older version of Internet Explorer, such as Internet Explorer 8 on Windows 7 Service Pack 1 (SP1), Microsoft recommends customers plan to migrate to one of the supported operating systems and browser combinations by January 12, 2016.”
If you haven’t done so already, make plans now to check and update Microsoft’s Internet Explorer browser. Last year Microsoft announced support for IE version 8 running under Windows 7 would be retired on January 12, 2016. Many people are still running Windows 7 with the IE 8 version. It’s important to update the Internet Explorer component soon. Not doing so could leave you vulnerable to security issues. Plus most web pages will run and look better if you upgrade your browser. Unless there is specific reason not to do so – such as application or hardware compatibility – your computers should use Internet Explorer 11.
