According to Microsoft, the end of support refers to the following:
Beginning 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.
This means ...
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 patch vulnerabilities that may be exploited by malware, helping to keep users and their data safer. Regular security updates help protect computers from malicious attacks, so upgrading and staying current is important.
Internet browsers are your portal to the Internet - they interpret websites and display them for you to review/interact with. However the Internet (and Internet technologies) have grown and developed at a rapid pace. And using an outdated browser will often mean that you cannot see the website as it is intended to be seen. Furthermore, you often open yourself to security vulnerabilities such as spyware, malware and viruses when using outdated browsers - which often don't come with the same level as security as their newer couter parts.
As with any software, it is important that you continuye to manage your software and upgrade to the latest versions (if possible). This announcement from Microsoft is a clear message to ensure that if you are using Internet Explorer - upgrade your browser to the latest version, or choose an alternative such as Firefox or Google Chrome.
