Hi. I have been looking on eBay to buy an XP OS disc for my new homebuilt computer project, but all of them seem to be $60 or more. There is a guy I know that can install XP plus a few more programs for $40 and still make money doing it... I wonder if anyone out there knows and could tell me. I wanted this to be a learning experience, but I'm also on a budget so that is why I am considering having him do it for me. I'm sure it has something to do with buying in bulk, but I really don't know. Just wondering. Thanks.
You want to be sure you are paying for a legit OS, not a pirated one. Many people can copy XP, and sell it to others. Then you're stuck with a pirated OS.
If you decide to buy from this person, go home and check the windows update site for updates. You may get promted for the WGA (windows genuine advantage) download. If you can successfully install that you're good to go.
