By the way, if you have to reinstall Windows from scratch there is a really easy way. Most computers these days come with a clean reinstall already on the computer. You use it by pressing an F key (F10, F12, etc) when you turn your computer on. Which F key depends on the manufacturer - you can try them all or google up your particular computer and "reinstall windows" - for example, "ThinkPad T400 reinstall windows."
