In a post called "The perils of using Internet Explorer as your default browser", Microsoft's Chris Jackson said everyone should stop using Internet Explorer. However, Microsoft kept Internet Explorer around for businesses as a compatibility option, not as a browser for everyday use.
Jackson clarifies that it's fine to use Internet Explorer where necessary, for example certain enterprise solutions, but even those companies should not be using IE as its default web browser.
We are not supporting new web standards for this, while many sites work excellent, large and developers are not experimenting and testing for Internet Explorer these days.
It's no secret that Microsoft isn't the biggest fan of the old Internet Explorer browser but since they introduced Microsoft Edge years ago they have been saying that they would not be supporting Internet Explorer. Rather than spending resources to make them compatible with the new-age browsers, they continue to use them because they were created to be used with it. They don't use Internet Explorer for the same, anymore.
Microsoft felt the need to kill off Internet Explorer in 2015 due to it being a compatibility issue. However, to be fair to Jackson, he never pushes for any specific web browser to replace Internet Explorer. Also when it comes out it should be good to use not just on the latest Windows 10 update but also on both Windows 7 and 8.
But if there's one lesson here to learn, it's that old habits-and desktop icons-die hard. The fact of the matter is that while most average internet users have moved on to Google Chrome, Firefox, or Microsoft's Edge, some businesses are still working with older web apps or sites that were designed for Internet Explorer.
