Google Chrome can be an an excellent browser for locked down public terminals, as the Windows version keeps itself and its integrated Adobe Flash plugin up to date automatically and completely transparently.
Using the normal download page, Google Chrome will install itself to the current user's home directory. Not a very good idea unless you want to install Chrome on a machine you don't have admin rights on. For a system wide installation in the
%Program Files%folder, which keeps itself up to date using Google Update's scheduled background tasks, one could previoulsy use Google Pack, which now has been discontinued.
The intent of this question is finding an answer to if and how Google Chrome can be installed system-wide now that Google Pack is defunct.
