Solved Lost Password !

I know this forum is for vista but i just wondered if anyone can help me help my daughter ! My daughters forgotten her password on her laptop, i have tried all the usual methods to get in to it but to no avail, in both normal and safe mode, we don't have the XP disc as she bought the laptop from a friend, i have even thought about downloading ophcrack but it seems a bit long winded and a little confusing, so has anyone got any ideas or knows how to get this situation sorted so that i can get her up and running again !
Thanks in advance !
