This tip applies to all editions and even previous versions (2012, 2012) of Visual Studio.
Since Microsoft has been releasing these updates e.g. VS2013.1 etc) the default behavior for these installers are to just download what is need at the time they are run. This is all good and well if you have only one machine that needs updating. What happens if you have to update a whole bunch of installs?
Luckily the VS2013.x installers support an undocumented (or not well) command line parameter ‘/layout’ that allows you to have the full update downloaded to a local folder. From there you can run the same installer without the parameter and it won’t download any additional stuff again.
Full command: VS2013.1.exe /layout
Happy downloading… only once.
