.. you may just have been given a shiny new computer. After the Windows 7 configuration part finally completes, remember to download ALL Windows software updates first, followed up by an anti-virus solution. I always suggest that Microsoft Security Essentials is used. When all is completed, you should be good to go..
See? Santa is busy setting his new Windows 7 machine up, and he is doing it right. you may have to trust me on this one..
Have a great time, try not to eat too much, and try not to fall over much either. You may not feel it at the time, but the bruises will still show..
