internet explorer is included in windows 10 along with the new edge browser.
just type internet explorer in the windows 10 search panel, you can then launch it or pin it to start or task bar.
(the internet explorer exe is located at C:\Program Files\Internet Explorer\iexplore.exe if you want to create a shortcut)
tv anywhere users might find this info useful if you normally use ie to watch it
