A new computer should not start up with a default user. A new computer should start up to the Windows OOBE (Out of Box Experience) which has the user set up their first account.
Its been so long since I've owned a retail machine I have no idea what an OOBE is :). Even when I do get retail/end user machines I usually replace/upgrade the HDD's or format/reinstall the OS before the first boot to dump the bloatware.
