Agreed with the above two.
Just reading those instructions while installing Windoze, can save a lot of headaches. Also install anti-virus (I like AVG Free) a better firewall (I like ZoneAlarm) and install a spyware scanner (I like SpyBot), also remember to install updates. If you follow all of the above (you can use the software of your choice) you'll be fine, and be as headache free as you can be using Windoze.
