when you buy a computer, lets say a laptop for example, a copy of windows (xp) SHOULD come with it or not?
Yes, it should. Unless it states that an OS isn't included. If you're not buying online, then ask instore
ha okay thank you... cuz im gonna buy one, and if the employee tells me that windows isnt included(xp whichs already installed)... i should ask for 1? right?
Well, it may come with an OS CD which you need to install XP yourself. Others come preinstalled. Just ask, ansd if there isn't one, get one
