Want to restore my laptop to its original condition?

you can download windows for free online. just find an .iso image file for windows 7, xp, or whatever you have, and download it. once it's downloaded, burn the image file (.iso) to a dvd-r disk. after that you'll need to buy a key online to make it genuine or find a patch or crack for it. which the second option is illegal and I don't advise it.
