I am not real computer knowledgeable, but I thought this computer would come with an operating system and a working hard drive. I also was not aware that the PC would be about 10 years old. I knew it was refurbished, but the refurbished ones I have bought in the past worked when I took it out of the box. If I didn't have a son who knows about computers and could make it work for me I would have had to send it back, having to pay the return postage. I will not recommend this company to anyone or order from them again.
