IE10 over IE11

You cannot re-install IE10 unless you are using IE9, you just need to uninstall IE11 and it will revert back to IE10.

This guide is for IE10, but all the instructions are the same, just substitute IE11 for IE10 in the instructions and make sure you follow the part showing you how to hide the update or it will get re-installed.
