Beginning with Windows Vista and Windows Server 2008, the name of the AD RMS client has changed to Active Directory Rights Management Services (AD RMS) client and is integrated into the operating system so that a separate installation is not required. In earlier versions of Windows, the client is named Microsoft Windows Rights Management Services (RMS) client and is available from the Microsoft Download Center as a separate downloadable component. The RMS client can be installed on the Windows 2000, Windows XP, and Windows Server 2003 operating systems.

The RMS client supports three different architectures: x86, x64, and Itanium. The download locations for each version of the RMS client are the following:

The AD RMS client requires little interaction from the system administrator who is administering the client computers. However, in more complex environments, it might be necessary to adjust the default AD RMS client configuration.
