How to make Registry Key changes using batch file or GPO or both

Hi Guys,

Below are the registry keys which I would like to install on our client computers. What do you think would be the best way of doing this?

StartUp script, loggon script or create a GPO to edit registry key (I don't think this option is viable as I couldn't find the office keys under HKCU in Group Policy Management Console).

REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\General" /v "SharedTemplates" /t REG_SZ /d "S:\RMWTemplates" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\General" /v "SharedTemplates" /t REG_SZ /d "S:\RMWTemplates" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\General" /v "SharedTemplates" /t REG_SZ /d "S:\RMWTemplates" /f

Note: Clients don't have admin rights on their computers.

Thanks in advance.
