How to change Windows user name in CMD

First check existing users in the system

open command prompt as administrator and enter

net users

Next

You can use wmic for this. The command is:

wmic useraccount where name='currentname' rename newname

Example, if your username is "user" and you want to rename to "user1" the following command would be used.

wmic useraccount where name='user' rename user1

Please note, you need administrative privileges to use this command, so make sure you start your command prompt using run as administrator.

EDIT: suddenly you mention in the comments that you do NOT want to change the Username, but the Full Name instead.

The command for that is here:

wmic useraccount where fullname='currentname' rename newname

You can substitute fullname or name for any of the following:

AccountType  Description  Disabled  Domain    FullName     InstallDate  LocalAccount  Lockout  Name   PasswordChangeable  PasswordExpires  PasswordRequired  SID  SIDType  Status

You can use the following command to see a list of all users with all their settings:
