These cumulative updates to Visual Studio 2013 include a variety of bug fixes and capability improvements.

The Remote Tools are intended for computers that don't have Visual Studio so that you can debug, test, and profile apps that are executing on them. Visual Studio must be installed on the development computer that's connected to, or uses the data collected from the remote computer. Connecting to the remote debugger included in the Remote Tools is supported in Visual Studio Ultimate 2013, Visual Studio Premium 2013, Visual Studio Professional 2013, Visual Studio Express 2013 for Windows, and Visual Studio Express 2013 for Windows Desktop.

Connection to the test features in the Remote Tools requires Visual Studio Ultimate 2013 or Visual Studio Test Professional 2013.

The Remote Tools also enable the installation of a developer license, deployment, debugging, and profiling of Windows Store apps on Windows 8.1 and Windows 8.

Support for Visual Studio 2013 is only provided on this current update, which is considered the Visual Studio 2013 Service Pack. The Visual Studio 2013 RTM version, released in November of 2013, will only be supported for one year after the release of this current update. For more information see the Microsoft Support Lifecycle Policy.
