In all the time I have been using computers, about 10 years now, I have never actually formatted one. I know what it is of course. The main reason I haven't is, since formatting wipes your HD, you would presumably have to reinstall windows. I have never owned an actual copy of windows lol. I have always had it pre-installed on my machine, from win 98 through to vista which I have now. If I formatted I'd be screwed since I wouldn't have a disk to reinstall it.
Anyone been in a similar situation? Should I just buy a copy of it lol.
