Do you know why that is?
I noticed that there are prominent links to a Korean and Japanese version, presumably because Internet Explorer is still used to a large extend in those two countries. Korea had some crypto stuff that only worked in IE, but that was years ago. Why haven't those markets moved on more modern browsers?
As for Korea, IE was mostly for ActiveX, but now most Korean website supports modern browsers ie Chrome.
This should be, and always should be, the case. Chrome is such a bad actor in allowing userspace install, we mark it as malware to prohibit unauthorized installation. Chrome Enterprise policies don't seem to be able to disable this, marking it as malware is the only way out...
That said, we offer two modern browsers to everyone in our environment, Edge and Firefox.
