From 15 June, the desktop app will be disabled and users will be redirected to Microsoft’s Edge browser instead.
Internet Explorer was the gateway to the internet for people born prior to Generation Z, in an era when Microsoft dominated the tech world, before Google, Facebook and TikTok, and when the browser had to be installed on to computers using a CD-ROM.
Microsoft’s market domination came about due to its bundling of the software as part of the Windows operating system. The experience was often sluggish and when faster competition arrived with Mozilla’s Firefox and later Google Chrome, people jumped ship in droves.
I'm sure this will be a total pain for some places such as law firms and private practices since they still rely on IE due to legacy software which I'm sure that MS will extend those contracts for now. In at all, this is a good riddance moment for the rest of us although we never forget how this browser was dominant, then it stopped innovating, then Google Chrome became dominant and it's now much like when IE was.
Also Japan is panicking for being so slow to adopt to new tech and methods:
