Hi, I`m afraid that you cannot uninstall it as it is an integral part of Windows, you can turn it off however if you wish. You can do this by going into control panel/programs and features/turn windows features on and off, but I guess that is not what you wish to do. However, you can restore a previous installed version (if you had one previously installed on your computer), go to the 'start button' select 'programs' and find IE and 'right click' on it and select restore 'previous version'. This will give you the version you had on your system before upgrading. Try that version and see if it works okay, then upgrade to IE11, hope this may help you.
