easiest way to create a win 11 local account is to enter:

press shift+f10(sometimes you need to hold fn key depending on device) then type:
oobe\bypassnro

another option thats more advanced if that doesnt work is the following

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” and press enter.

Next type “net user Prefferedusername /expires” and press enter.

Next type “net user administrator /active” 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.
