What is end of support?
From today, January 12, 2016, only the most current version of Internet Explorer available for a supported operating system will receive technical supports and security updates. Internet Explorer 11 is the last version of Internet Explorer, and will continue to receive security updates, compatibility fixes, and technical support on Windows 7, Windows 8.1, and Windows 10.
What does this mean to me?
It means you should take action. After January 12, 2016, Microsoft will no longer provide security updates or technical support for older versions of Internet Explorer. Security updates help to address vulnerabilities that may be exploited by malware. Regular security updates and patches help protect computers from malicious attacks, so upgrading and staying current is very important.
