Accounts :: Locked Out Of Administrator Account

I am currently on a different computer than the one where I am locked out of the Administrator account.

Less than 3 weeks ago, I bought a new laptop that came with Windows 10 installed. When I finally set up the new laptop and tried out Windows 10 for the first time, I was annoyed at the whole thing with Windows blocking some programs from being installed and a lot of other annoying prompts. This is when I found out about a higher level of Administrator access known as a Super Administrator to avoid most of these prompts, and install programs without being blocked by Windows. So what I did created a new user account with the Command Prompt and gave it Super Administrator access without setting a password. Once I logged into my new user account, I deleted all of the other user accounts on my computer, since I had no need for the other user accounts (such as the Guest account).

The real trouble happened when my computer crashed and experienced a BSOD. After the computer rebooted from the BSOD, I found out that I could not log into the Administrator account because it prompts for a password, but I never set up a password for the account. Inputting no password does not work. I am not sure how a password was set up on the Administrator account without my knowledge and whether this might have been related to my BSOD crash.

I have made an attempt to get back into my only user account, but nothing has worked so far. All of the built-in Windows diagnostic tools have failed to work, since they all require that I log into the Administrator account, which I am unable to do. My original plan was to use the option to reset my PC that lets me keep my files, but that won't work without having access to the Administrator account. What password is on my Administrator account considering that I never set up a password and somehow the account now has a password on it. How to get back into my Administrator account?
