Solved I have a huge problem regarding the loss of my Admin password

[skittlyrainbow]

Quite a few years ago I had an old Windows Vista laptop given to me and I fixed it up and personalized it. I added a guest account with extremely strict parental controls, as I intended it to mainly be for internet use. Years later I have a new Windows 10 computer and I found the old laptop. I really want to restore it and use it for something else, but I forgot my Admin password. I've tried the safe mode idea, but it doesn't let me get in because I had changed the Admin password. Right now I can only access the guest account in which I can only download files from the internet and move them(but not open them). I even went as far as to burn Ophcrack to a disk, which was successfully booted, but it says it cannot find the password. There was only one password I used at the time, but I tried every password I've ever used and every version of each and It still won't work. Please help me unlock my computer, and thank you in advance. My available materials are listed below:
A stack of blank DVD-R disks(4.7GB), Ophcrack burned onto a DVD-R disk, Windows 10 computer(no disk drive), An old Mac(with disk drive, borrowed from a friend), 8GB flash drive, Windows Vista laptop(with disk drive to boot from). I do NOT have a license for Windows Vista, so I cannot burn the OS to a disk to boot from.

I have a password removal boot disc on my site that I find better than Ophcrack
