Windows 10: Admin account on computer

How to change admin user account name?

ah so main admin account is 'wizzle' which is what I am currently on
I make another account called 'wizzle2' (with admin rights)
I sign out of 'wizzle' and sign into 'wizzle2'.
And once signed into 'wizzle2', then I do the command prompt step and find the SID for 'wizzle' that is listed and go from there?
