Forgotten administrator password

[Shawn]

I made an administrator account on my sons computer to control what he can and cant do. However now I cant remember the password for the account to log in. I tried starting in safe mode but it still brings up the two different accounts and ask for the password. I tried to put his "recovery cd" in but I found he did not copy the files to the cd. I am now taking the motherboard battery out to see if that works. Any other suggestions?

ok I figured it out. I had to download a program called "Ophcrack." It was free and the number one password recovery program. I had to download the program to a cd, make the cd a bootable cd, and then make sure the boot sequence started with the cd drive. I ran the program and it showed me every account that was made and the password to each account. To ensure this never happens again I made my son the administrator and deleted my account. He is much younger and can remember better than I.

I just use the chntpw package.

I have modified this for custom use.
