Final answer:
Administrators can remove a user in Windows using the GUI in Computer Management, the CLI with 'net user [username] /delete', and PowerShell with 'Remove-LocalUser -Name username'. Option B is incorrect due to a non-existing command syntax. Options A, C, and D.
Step-by-step explanation:
The methods Administrators can use to remove a user in Windows are the following:
- Using the GUI: Under Local Users and Groups in the Computer Management tool, right-click the user and select Delete.
- Using the CLI: The correct DOS-style command is net user username /delete.
- Using PowerShell: The command Remove-LocalUser -Name username is used.
Option A is correct as it describes the standard procedure for deleting a user via the graphical user interface.
Option B is incorrect because the demonstrated command does not exist in this form for user management.
Option C is also correct but with a minor modification—the correct syntax is net user [username] /delete.
Lastly, option d is correct as it shows the PowerShell command to remove a local user.
Hence, the right answer is options A, C, and D.
