You can download VS 2013 Update here: http://www.visualstudio.com/downloads/download-visual-studio-vs/. The only thing I actually do not prefer is that the Update 4 is 7GB. The size of an update is bigger than the size of the VS 2013 installer.
I think VS team should think of how to reduce the update file size in future. Many countries in this world still connecting to Internet with 1Mb / sec. Does that mean Visual Studio only can be used in those advance countries?
