RDP 8.1 updates for Windows 7
These fixes update the Remote Desktop Services server-side roles and components that are built around Remote Desktop Protocol (RDP) 8.1. However, although updates are performed on the server-side infrastructure, the Remote Desktop Clients are often left untouched. This can cause performance and reliability issues. By default, older clients such as Windows 7 Service Pack 1 (SP1) are restricted to RDP 7.1 and do not provide the new features and improvements that are available in RDP 8.1. Therefore, we have released the RDP 8.1 client for Windows 7 to provide significant performance and reliability improvements when these clients are connected to RDS 2012 R2 environments. For more information on Windows Update, please see the dedicated FAQ from Microsoft.
