Summary: Microsoft announced today that it's dropping support, including security updates, for older Internet Explorer versions. The changes, which take effect in 18 months, are meant to push the vast Windows installed base to Internet Explorer 11.
If you’ve stubbornly resisted upgrading Internet Explorer on an older PC, you might be forced to act soon. (Of course, if you work for a company that has stubbornly insisted on making you use an ancient version of IE, this is good news.)
Starting January 12, 2016, Microsoft is changing its list of supported Windows configurations. Effective that date, the company said in
an announcement today, “only the most recent version of Internet Explorer available for a supported operating system will receive technical support and security updates.”
