When it is new it will initially be configured. When a new
operating system is installed, it will be configured. Installing
some software or changing some settings may require a little
re-configuring. If you are chaning the country settings, for
example. If the computer is being connected to a network it may
need to be configured. If it is being upgraded it may be
configured. If it is having a complete change in usage, maybe as a
server instead of a client it may be configured. So there are many
reasons when a computer would be configured.
