SOS

i want to make a new user account on windows 10, but the account i use is a standard user. i know how to make an account, enable the built-in admin account, etc. by using settings, cmd prompt, run, and control panel, but i can't do any of that because my own account is a standard user. my mother has an administrator account on the laptop that i don't know the password to.

so basically, my question is--how can i make a new administrator account, change my own account to an administrator, or figure out my mother's password with a standard user account?
