After you configure shadow copying, you must install the client on computers throughout the organization. The client installs a new tab called Previous Versions on files and folders that are shared.
Before users can access previous versions, the client must be installed on their computer. Two clients are available:
Previous Versions Client
Shadow Copy Client
You can use Group Policy or SMS to distribute either client. You can also simply copy the file to a user's computer. Both clients are made available as MSI packages that require Microsoft Windows Installer 2 or later, which is available automatically on Microsoft Windows XP or later versions of the Windows operating system.
