Beginning January 12, 2016, only the most current version of Internet Explorer available for a supported operating system will receive technical support and security updates," the software giant announced on its website.http://www.bbc.com/news/technology-35291938
NetMarketShare estimates that Internet Explorer accounts for 57% of the browser market, compared with 25% for Chrome, 12% for Firefox and 5% for Apple's Safari.
According to Computerworld, some 340 million people still rely on older versions of the IE browser.
It has led security experts to warn of a security "hot potato".
"It is safe to assume that cybercriminals have been stockpiling IE vulnerability information ahead of the support cut-off," said Craig Young, a researcher at security firm Tripwire.
