System Recovery - Troubleshoot - Advanced Options - Requires Administrator Password but No Account

[u20210512]

I just purchased a desktop, and I have not loaded the operating system yet. I have entered the BIOS setup and System Recovery only. Again, I have not loaded the operating system once. However, when I access the System Recovery > Troubleshoot > Advanced Options these utilities require an Administrator password Startup Repair, Startup Settings, Command Prompt, Uninstall Updates, System Restore; but as I said, I have not loaded the OS yet, and I am not aware of any Administrator accounts. 

When I click the "Forgot your password or don't see your account?" I get the following message:

This list only shows administrator accounts that have previously signed in to this PC, and does not include standard user or domain accounts. You need to be signed in as an administrator to use some repair and restore tools. If you don't have a password for any of these accounts, you can restart to try signing in to Windows to manage your user accounts.

This video illustrates the password and description of the password I am being asked for: https://www.youtube.com/watch?v=fEfmZGIepU4

Again, I have not loaded the Windows operating system et all, so what is this administrator password am I required to enter?

Thank you
