I unintentionally set a password that I don't remember

I often get a message that I must submit permission to perform some action like delete a folder. Apparently I unintentionally set a password that I don't remember for the administrator account. Fortunately this is on my laptop which has no important files that are not also on my desktop so losing data is not a huge issue. I want to try the steps in the tutorial Brink suggests but I don't see an administrator account in the user accounts but there is a folder for it. I'm kind of lost at this point about where to work on the problem.

BTW: This is one of those machines that came with Vista with a free upgrade to Win7 so I don't have Vista installation disks.

First try to create another Admin account and name it Admin1, then try to delete the original Admin account. Second if that did not work. I am not sure if I should mention this or even advise this but I guess we will find out. Google "ophcrack" and down load to a cd or dvd disk. Then resart the laptop with the disk in and let it run and it shoud find your password. As for not having any Vista Discs you can purchase a set of discs for a very reasonable price from http://restorediscs.com .
These are just suggestions someone with more experience may have other advice or suggestions.
