Windows Vista Admin Password forgotten

[chezchat]

Can anyone help. My has has for some reason re-set his Administrator
password and forgotten what he set it to (don't you just love em) I have the
Vista disc but don't know how to reload vista as when I try it still asks for
the Admin password. All he can do as work on the internet as everything else
asks for this password. I am afraid to experiment in case I mess everything
up although he doesn't have anything saved or in files as he only had the
system at Christmas. We got it from Mesh but I have tried without success to
get help from their helpline, in fact I can't even get my calls answered.
Any help would be gratefully received.

Thanks for the help but the system restore date only goes back to the
beginning of March and this problem has been going on for longer than that.
I ticked a box for more restore dates but still only got March. I think I am
going to have to completely reinstall windows but don't know how.

Thanks Brink but I don't like the look of using method 3. On the FAQ there
seem to be so many things that could go wrong and it will be just my luck I
will have one of them. As my son has done nothing on the PC since he had it
than use the internet I think the safest to just reinstall Vista. I just
need directions on how.
