User script do not work over computer object

I have scenario using Windows 2012 active directory.

I have multiple Windows server 2008 R2 and I want to create some registry association.
I want to set these settings only on one OU. This OU have 8 servers.

Basically what I am doing is:
I create and User (Not Computer) based settings and I want to it apply on computer (not user) objects. User based settings are not supposed to apply on computer objects. But there is a workaround.

I need to set some computer settings:
Computer Configuration
Policies
Administrator Templates
System
Group Policy
