“IE has been removed from Windows 10 and 11”
Yes, it’s not an integrated part of the OS anymore, but it could still be installed and used prior to this latest update.
“...no one should use it.”
Well, that’s one opinion, but there are certain situations where people simply have no choice in the matter.
Unfortunately you are correct. Even thought IE has more bugs than a Great Reset meal plan there are still some old sites that will only work on it.
