I recently attempted to assist a friend with their computer which uses windows xp. I ran anti-viruses on it and removed viruses on the pc, but this damaged the registry and made error messages pop up constantly. Next i tried to load an older version of Windows xp and ran the repair option. this seems to have fixed the registry problems but now it wants a code for the version of windows, apparently not the same version now as the one that was on the pc, as i tried to enter that code but it won't accept it. Also, now it will not access the internet and i cannot figure out why. Please is there any way to recover the version of windows xp that was on the pc?
