INFORMATICS

In Windows environment, each user is assigned a unique identifier called Security ID or SID, which is used to control access to various resources like Files, Registry keys, network shares etc. We can obtain SID of a user through WMIC USERACCOUNT command. Below you can find syntax and examples for the same.

Get SID of a local user

wmic useraccount where name='username' get sid

For example, to get the SID for a local user with the login name  ‘KARL, the command would be as below

wmic useraccount where name='KARL' get sid

Get SID for current logged in user

To retrieve the SID for current logged in user we can run the below command. This does not require you to specify the user name in the command. This can be used in batch files which may be executed from different user accounts.

wmic useraccount where name='%username%' get sid

Get SID for current logged in domain user

Run the command ‘whoami /user’ from command line to get the SID for the logged in user.
Example:

c:\>whoami /user
USER INFORMATION
----------------
User Name      SID
============== ==============================================
mydomain\wincmd S-1-5-21-7375663-6890924511-1272660413-2944159
c:\>

Get SID for the local administrator of the computer

wmic useraccount where (name='administrator' and domain='%computername%') get name,sid

Get SID for the domain administrator

wmic useraccount where (name='administrator' and domain='%userdomain%') get name,sid

Find username from a SID
Now this is tip is to find the user account when you have a SID. One of the readers of this post had this usecase and he figured out the command himself with the help of the commands given above. Adding the same here.

wmic useraccount where sid='S-1-5-21-1471586919-1128665872-1817863081-504' get name

Runas i uruchamianie programów na innym koncie w Wierszu Poleceń

Systemy Windows posiadają wbudowane polecenie „runas” służące do uruchamiania poleceń jako inny użytkownik. Oto przykłady:

runas /user:Domena\konto program.exe

Przykład uruchomienie konsoli jako administrator

runas /user:Administartor cmd.exe

Po wciśnięciu ENTER, konsola zapyta nas o hasło dla użytkownika administrator. Nie można podać hasła jako parametru.

Jeśli mamy potrzebę wykonania kilku poleceń, nie trzeba każdego z nich uruchamiać przez runas. Można jednorazowo uruchomić sobie konsolę CMD, a każde polecenie w niej wpisane będzie miało odpowiednie uprawnienia.

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:

wmic useraccount list
