Talk Web browsers and all you get is misinformation.
Windows 8 comes with IE 10, Windows 8.1 comes with IE 11.
With Windows 8, Windows Updates should list IE 11 as an update.
It is always best to go to the main man, rather than some other website.
Bing is not forced on you either, in IE 11 like earlier versions, you can add other search engines and make them the default if that is your wish.
I use IE 11, have Google as a default for both Search Engine and as an Accelerator. Nothing bad happens.
