Garry the hard drive has a partitioned boot sector which, when activated by pressing F10 on startup will restore your computer to its original setup as it was when you took it out of the box. you will however loose everything you did since. It is also possible that if you ever set up a restore point in windows that you can go back to an earlier time (time travel: weeeee) to do this start the pc click on start and click on help a pop up window will appear and this will have a range of options . On the right hand side somewhere will be the option to set up or return to a restore point. I can't remember the exact wordng right now and i'm not at home so I can't check. using this option will allow you to wind back the clock to an earlier time but relys on you having entered a restore point in the past. Very Authur C Clark. Hope this helps
