Internet Explorer or IE is the default browser on Windows. If you’re looking to use this app on Chromebook to browse the web, the best advice is don’t. Chrome OS is built around the Chrome browser, which you are using to access this website, and it is a lovely replacement for IE.
However, if you need to get access to IE for testing or similar purposes, there is an app for that.
Cloud Internet Explorer
The Cloud Internet Explorer app gives you a short time accessing a remote Windows box running a version of IE (no flash enabled), so you can see how the other half sees your website.
