Manage IE 10 preferences with a 2012R2 Server in a 2008R2 Domain

Hi all,

We would like to upgrade from IE 9 to IE 10. I've learned that you can't manage the GPO from IE 10 with a 2008R2 Sever but you tweak the XML files. That's no option for us therefor we've installed a 2012R2 Sever in our 2008R2 Domain.

We've copied the inetres.adm file from 2012R2 to the 2008R2 DC

Now we have the posibility to create IE10 preferences on 2012R2 but we can't see and manage them on our 2008R2 DC.

My Question is:  Does the preferences still apply on our clients or do we need to uprade the DC to 2012R2?

With best regards David
