Why do people/companies still use Internet Explorer?

I think IE 11 is an industry-wide pain since it hasn't kept up to date in recent years, also, Microsoft's pledge to support it for the lifetime of Windows 10.

I recently surveyed 500 E11 users with a poll asking if they had other options, and I found that most users had a different browser already, about 7% borrowed a computer from a friend and 7% was locked in by their IT-department. I did have 20% in other reasons (which I didn´t explore, but I think since I exemplified such as Chrome/Edge/Firefox some users of other browsers like Opera might have selected that option. some in others had windows 8.1 but many with windows 10)

So, I think the answer for IE11 traffic is: Mostly happenstance and old computers. It will give some users some pain if you drop it completely.

The IE11-users was single out by triggering hotjar with

<script language="javascript">
if (window.msCrypto) {
    hj('trigger', 'ie11')
}
</scriipt>

This is because of legacy applications which are built decades ago and they are still supported to avoid any potential disruption to business processes. Apart from that from my enterprise experience what I can see is many other factors also play a role for this legacy support like

1. IT of the company doesn't care about embracing change or new apps/features/technology due to the existing policies and company directions.It's a huge overhead to change any. 2.Legacy apps have to be supported till the business process is live. 3.Big companies have few tie ups with vendors and they provide few add on values in terms of softwares or licences to use certain apps for less cost than competitor in the market. 4.Mindset change ! i.e to embrace change which is mostly lacking in business users who actually use old software/apps. They just really don't care till it solves their purpose.

Only way to get out of this loop is companies like Microsoft/Google and others should come up with less LTS or provide free/less cost upgrade policies, then only change can happen.

In software industry everything is tied to money ! Things change only if doesn't cost you extra or you don't have an other option ;)
