I do not understand the purpose of your post. You ask how to do something and then at the end provide an answer.
Your solution is not a viable one though. If it were that simple to reset that password the password would have no value.
If this is actually your problem then post back verifying the solution actually worked.
If you are just a troll trying to post methods to circumvent security measures then hopefully one of the mods will remove this post and possibly ban you.
It has been past practice that we don't help with laptop passwords.
