A few typos were brought to my attention in my previous comment and as the time frame to edit it has passed I am replying with the required edits so that if anyone does want to attempt this they don't have to wonder what went wrong
I originally had “ net user Prefferedusername/active:yes” but there should have been no space before "net" and I should have put a space before the "/" after prefferedusername.
so the corrected instructions are below. (hopefully without typos this time)
at the first setup screen instead of answering any of the questions press Shift + F10
CMD will open
Type (no quotes) “net user Prefferedusername /add” (replacing Prefferedusername with the user name you wish to use) and press enter.
Next type “net localgroup administrators Prefferedusername /add” and press enter.
Next type “net user Prefferedusername /active:yes” and press enter.
Next type “net user Prefferedusername /expires:never” and press enter.
Next type “net user administrator /active:no” and press enter.
Next type “net user defaultUser0 /delete” (this is case sensitive make sure the "U" is capitalized) and press enter.
Next type "regedit" and press enter.
This opens registry editor, navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE"
Delete "DefaultAccountAction", "DefaultAccountSAMName", and "DefaultAccountSID"
Right click on "LaunchUserOOBE" and rename it to "SkipMachineOOBE" and make sure the value is set to "1".

Close registry editor and type "shutdown /r /t 0"
