Turn Off Infocenter\Live Updates\Help in Autocad 2013

Hi,

I am using the Autocad 2014. In the top right side of the Autcad2014 I can see the following features.

Search, Sign in , Live Updates and Help.

I want to hide those features permanently. I have tried the following steps in the registry to hide Infocenter mentioned in various forums, but still I can see those features.

1. Modified the InfoCenterOn to '0'

2. EnableCommunication.. to '0'     

Is there any other way or configuration files which  I need to modify to turn off those features.

Thanks

Kannan
