Hello i recently bought a labtop off my friend that he bought from ebay but couldnt log on so he sold it to me for cheap, well the problem is that we cant log into windows at all, seems like some company owned it before because is isnt the normal xp login can you guys help please? The labtop is a Dell Latitude D620 and why does it have a windows vista sticker on the keyboard and have the vista product key on the bottom of it but says windows xp on start up? p.s only came with charger and labtop no disk's or anything thanks you
