More configuration
Things are going well so far, aren't they? It almost gets more complicated at this point.
Choose a name for the computer (make it unique if it's going to be on a network) and also create an administrative password. Don't make it too easy to guess, but don't forget it either, as you made need to use it if ever anything goes pear-shaped with Windows.
Now's your chance to setup the date/time (if it's wrong) and the time zone. As you'd expect of a Brit, I set mine to GMT with the daylight saving option ticked.
Networking
If you have any network devices (modem, NIC, etc) in the computer, Windows will now install network devices.
Following this you'll be asked what settings to use. As in the above image, you'll be fine choosing the typical settings and clicking next.
Next you'll be asked if your machine is part of a domain or not. If you have a small home network, choose the top option and think up a workgroup name. Multiple computers with the same workgroup name can share files across the network easily.
Windows Setup will now do yet more installation, under the guises of 'copying files', 'saving settings' and so on. Depending on the speed of your computer, this will take between a few minutes and many minutes.
