Q: i hear people saying that they need to format their laptops, what is is? and what does it do?
A: It restores your computer to it's original state, what I mean is that it deletes everything in your C disk, that is software, data, everything, including errors and viruses, which is the main reason a lot of people format their computers, and leaves only the software that came originally, basically it leaves the computer in the same way that it was when you bought it.
