Internet Explorer 10 comes preinstalled with Windows 8 Release Preview.
Unfortunately you cannot uninstall or downgrade to lower versions of Internet Explorer.
I just found you can go to a web page you need in an older version of IE and press F12. Then click on "browser mode IE 10" and you can change all the way back to IE 7. The downside is you have to do it every time but at least there is a way to access:)
