On a Windows 7 computer, you will need to add the Remote Server Administration Tools (RSAT) to gain access to the Group Policy cmdlets. You will first need to download the RSAT tools for your platform, either 64 bit or 32 bit Windows 7.
Once you have downloaded and installed the proper RSAT package, you have to go into Control Panel/Programs and Features and choose Turn Windows Features on or off. This step requires admin rights.
The RSAT package adds the Remote Server Administration Tools item in the dialog box. The dialog is shown in the following image.
