Windows Administrator Password

[echokilo]

Previously posted in "How It Works" - but it's been suggested I may get more help here (TIA) :

I need to install Norton upgrade on my dad's laptop and we can't remember the administration password for three original main user. This was not a problem previously esd there was only the main user account on there ..... but after a virus problem earlier this year I created a second user for him .... now how can I find tter password or how can I reset it please ?

Here is the origianl (identical questions if anyone wants to refer: http://www.theanswerbank.co.uk/How-it-Works/Question1200732.html)

Many thanks for any further help that can be given.
