Finally Adobe and Microsoft are getting along with each other (kind of). With Acrobat XI, they have released a zip file with ADM and ADMX starter templates to control SOME features of Acrobat, one of them being updates.
They call these “starter” templates because they were too lazy to create the whole thing themselves. The good news is they do publish all the possible settings so you can easily modify the templates to suit your needs.
You can find everything here: Acrobat GPO Starter Templates
Good luck.
