Internet Explorer – Microsoft would like you to stop using it
You see, Internet Explorer has a compatibility solution. Microsoft are not supporting new web standards for it and, while many sites work fine, developers by and large just aren’t testing for Internet Explorer these days.
They’re testing on modern browsers – Google Chrome – Firefox – Edge .
This means if you are still using Internet Explorer you will be missing out on the true web experience and you will be less secure.
On a similar note Office 2019 is now out but Microsoft would prefer you to get the subscription-based version of Office – Office 365
Office 2019 will not have any new features added to it , while Office 365 is always being updated with new features
