Here we start Deploying Remote Server Administrative Tools on client computer.You can install Remote Server Administration Tools (RSAT) as a Feature in Windows Server 2012. However, for Windows 8, RSAT is a separate download available at http://www.microsoft.com/download/details.aspx?id=28972.
Deployment of this package is accomplished on the client computer by double-clicking the installer, as detailed at http://technet.microsoft.com/en-us/library/hh831501.
Previous versions of RSAT required additional deployment to enable specific tools. The latest version of RSAT doesn’t require this step; the tools are installed when the package itself is installed.
