you should have the product key for this.
Dell has your product key listed on the bottom of the laptop and the type of Operating System it belongs to.
Unless you have a FULL version of the Operating System, that belongs to the laptop and/or recovery disks, You'll have to contact the person you got it from. Dell may or may not be able to help you. There should be a service tag on the bottom.

I bought a Dell Latitude laptop off eBay (I know, first mistake) that was already loaded with windows xp pro and several other programs. I used it for about 3 months very happy - then all of a sudden I got a message that my key for windows was not authentic. Well, of course I didn't have a cd or key sent with the computer. I do have an authentic windows xp cd but I can't use the key because it is on another computer. I also have an authentic windows 98 with a key that I could install, however, I have no idea how to format windows xp pro. This lap top does not have a floppy, so I can't use a boot disk. I also have a windows xp home edition for a dell that came with a battery (again off eBay) but don't have the key for it either. I really don't want to have to buy any software because at this point, I am broke! Any suggestions?
