IE 10 came pre-installed on a new PC. It conflicts with some engineering software that our company uses. We cannot use anything newer than IE9. How can I remove IE10 and load IE9? IE10 is not in the programs list to uninstall. I tried to turn it off and just load IE9 and got a message saying IE9 was already installed. To me, that says IE9 was installed and then upgraded to IE10 but the update history does not show any IE10 updates.
