Microsoft got rid of internet explorer in windows 10, you will have to use Edge, or another browser like Chrome or Firefox.
Take a little time to get to know how to use the " Edge ". It's a lot better than IE and almost as good as Chrome. Learn the Edge first before you decide to try another browser. I like the Edge just fine. Just takes some getting used to is all as it's new. In time, you'll forget about IE. I'm getting to like it better than Chrome and a lot better than Firefox. Stay with it a while.
