The folks over at Tech ARP have written up a beginners guide to installing the Windows Vista OS.
The process is quite similar to Windows XP installations with only minor additions in the look and feel.
What's interesting though, is that the installation process does not require the user to enter in a registration key. In fact, they can choose any Windows Vista version they want to install. A piracy plan waiting to happen (Or a piracy plan that's already happened...)?
