IE 10 - Win7 - GPO to set as default Browser?

Greetings,

I am in need of a way to set IE as the default browser for IE10 on Windows 7. I have searched Google, installed the IEAK for 10 and the Adm Template and I can't find a way to set IE at the default for my clients. Am I missing an easy setting or has MS made this impossible to do?

Thanks, 

Robert
