Another alternative, which is a bit drastic.
Format the system, reinstall Windows XP. Since you got the laptop from a friend, it may have things you don't want or need. You can then install what YOU want and need. Personally, if I got a computer from a friend, the first thing I would do is reinstall the OS IF that friend didn't do it just before he/she gave me the thing.
A reinstall will be done either with disks that came with the laptop and the friend gave them to you OR there could be a recovery partition installed on the computer. This partition will contain everything you need to reinstall the OS.
