How to Add User to Local Administrator Group in Windows 10

A limited user, unlike a user with administrator rights, does not have access to system controls. It is only with administrator privileges that a user can modify settings, install applications, administer elevated tasks, and achieve pretty much anything on the computer.

Scroll down to find how to add a user to the local administrator group in Windows 10 granting them access to system functions. In this guide, you will discover how to add a user to the local administrator group using Computer Management, Command-line, and Powershell.

Method 1. Add User to Local Administrator Group in Windows 10 Using Computer Management

Computer Management is a Microsoft Management Console snap-in that allows you to host administrative tools to manage system components, computer services, and networks. Not only on your computer but also on other Windows machines (that you have access to) on the local network.

Computer Management also allows you to add a user (on the network domain) to the admin user group to share the administrator rights; however, make sure to access Computer Management with the administrator privileges.

Note: Local Users and Groups is accessible only on Windows 10 Professional, Education, or Enterprise editions. If you are handling Windows 10 Home Edition, skip to Method 2, i.e., add a user to the local administrator group using cmd.

Follow these simple instructions to Add User to Local Administrator Group in Windows 10:

Step 1: Press Win + R (Windows logo key plus R) at once to open the Run box.

In the run box, type compmgmt.msc and click OK.

Method 2. Add User to Local Administrator Group in Windows 10 from Command Line (CMD)

Follow these easy steps to add a user to the local administrator group using the command line:

Step 1: Open an elevated Command Prompt.

Hover to the Search menu and type Command Prompt (or cmd). Choose Run as administrator.

Step 2: You can view all the added local groups by typing:

net localgroup

Press Enter once you type the command.

net localgroup Administrators {username} /add

Press Enter.

Here “test” is the desired user name.

Executing the net localgroup command, you will successfully Add a User to the Local Administrator Group using cmd, i.e., command line.

Method 3. Add User to Local Administrator Group in Windows 10 Using Powershell

Microsoft Powershell, like Command Prompt, is a command-line shell but with added features that can execute scripting/cmdlet instructions—making it more compelling than the command prompt (the above method of adding a user to the local administrator group).

Follow these simple instructions to add a user to the Local Administrator Group using Powershell (in Windows 10):

Step 1: Press Win+X (Windows logo plus X keys) together, from the list of options:

You will see a message saying: The command completed successfully.

Create a new local user to the local administrator group

To add multiple users to the local administrator group at once, type this command instead:

Add-LocalGroupMember -Group "Administrators" -Member "User1", "User2", etc...

You can review the modifications by opening the netplwiz through the Run box:

  1. Press Win+R keys at once; this will open the Run box.
  2. Enter netplwiz in the Run box.
  3. Click OK.
  4. Under Users, you will see the added user in the User Name section. From the Group, you can examine if the user has administrator privileges or not.

Note: Due to variable system configurations, the above script might not work on some computers. If that is the case, try using this script instead to add a local user to the local administrator group using Powershell:

Copy the script (given below) to a text editor on your computer.


$Username = "USERNAME"
$group = "Administrators"

$adsi = [ADSI]"WinNT://$env:COMPUTERNAME"
$existing = $adsi.Children | where {$_.SchemaClassName -eq 'user' -and $_.Name -eq $Username }

if ($existing -eq $null) {

Write-Host "Adding local user $Username to $group."
& NET LOCALGROUP $group $Username /add

}
else {
Write-Host "Adding to administrators group $Username."
$existing.SetPassword($Password)
}

Write-Host "Ensuring password for $Username never expires."
& WMIC USERACCOUNT WHERE "Name='$Username'" SET PasswordExpires=FALSE

Replace the USERNAME with the desired user name.

  1. Copy the edited script.
  2. Open Windows Powershell with Admin rights (Win+X).
  3. Right-click to paste the code.
  4. Powershell will add the user to the local administrator group automatically, no need to press Enter.

Conclusion

You can work on any of the three methods discussed to successfully add users to the local administrator group on Windows 10. However, the first method, i.e., add a user to the local administrator group using Computer Management, is not accessible on Home editions of Windows 10; still, you can employ cmd or Powershell.
