How to: Install Visual Studio 2012 Update 1 Offline

Inspired by Rob Caron's blog on installing VS2012 Update 1 offline. Below shows how to download without user interaction with the GUI.

C:\> vsupdate_KB2707250.exe /layout f:\tmp /passive

Of course you need to download the installer first, see this link. It is assumed that vsupdate_KB2707250.exe is in the system path or in the root of drive C:. And you have enough space in drive F:\.
