IE11 runnig in compability mode us GPO

Hi,

Does someone know if there is GPO setting that will force IE11 running on clients, to run in IE10 or IE9 compability mode?

A number of our clients have manually installed IE11 on their computers wich now prevents them from running a specific business application that runs in IE.

These users have to be local admins on their machines unfortionally so we can´t prevent them from installing updates.

There is a GPO that removes some links to WU/MU i know, but these are clever little users.

Thank you
