This article describes the Remote Desktop Connection (RDC) 8.1 client update that lets you use the new Remote Desktop Services features. These features were introduced in Windows 8.1 and Windows Server 2012 R2, and they are now available for computers that are running Windows 7 Service Pack 1 (SP1).
New features for remote connections to Windows 8.1 or Windows Server 2012 R2The following new features in the RDC 8.1 client update are available when you establish a Remote Desktop Connection session to Windows 8.1 or Windows Server 2012 R2.
Support for faster reconnection timesThis update reduces the time that RDC 8.1 client takes to reconnect to a remote session compared to the time that is taken by the RDC 8.0 client and earlier versions of the client. The actual time that the client takes to reconnect depends on the network and deployment configuration.
Dynamic monitor and resolution changesAfter the update is installed, RemoteApp programs and desktop sessions behave like local programs when you add, remove, rotate, or change the resolution of the local client. For example, when you apply rotation, the width and height is changed accordingly on any RemoteApp programs, and the resolution of a desktop session is also adjusted.
Support for session shadowingWindows Server 2012 R2 and Windows 8.1 let administrators use the session-shadowing feature on a session-based or virtual machine-based desktop or on a RemoteApp application. This is very useful for the support and troubleshooting of an end-user problem. By using RDC 8.1, administrators can now use the session-shadowing feature from the command line on Windows 7 SP1-based computers.
New features for remote connections to other versions of WindowsThe following new features in the RDC 8.1 client update are available when the clients connect to all versions of Windows.
Remote Desktop Gateway pluggable authentication and authorizationRemote Desktop Gateway pluggable authentication and authorization (PAA) let you use custom authentication routines with Remote Desktop Gateway. Since RDC 8.1, the PAA cookie can be provided as an RDP file property in addition to the existing ActiveX API and Internet Explorer cookie-based methods. This can be used to provide custom two-factor authentication that works seamlessly with Remote Desktop Web Access (RD Web Access) across multiple browsers. This functionality lets you use RDP files to start connections.
Note This feature requires the Remote Desktop Gateway server to be running Windows Server 2008 R2 or a later version.

PrerequisitesTo apply this update, you must be running Windows 7 SP1. Additionally, the following updates must be installed:
Co-existence with the RDP 8.0 updateThis update does not include Remote Desktop Protocol 8.1 server-side components for Windows 7 virtual desktops. In other words, this update includes only the new client. Therefore, the update applies only to computers that will be used as client computers. The RDP 8.0 update includes both the RDC 8.0 client and the RDP 8.0 server-side protocol components for Windows 7 SP1 virtual desktops. If you want to have both the RDP 8.0 server-side components and the RDC 8.1 client installed on the same computer, you must first install the RDP 8.0 update and then later install this update.
