A technician is required to change a setting for HKEY_Local_Machine. Which of the following would the technician use to change this?

BCDEDIT is a command-line tool for managing Boot Configuration Data (BCD), not for editing registry keys.

WEP setup refers to wireless network encryption configuration and has no relationship to Windows Registry editing.

MSCONFIG (System Configuration utility) manages startup programs, services, and boot options but does not provide direct access to edit registry keys.

REGEDIT (regedit.exe) is the built-in Windows graphical tool for browsing and editing the Windows Registry, including all root keys such as HKEY_LOCAL_MACHINE, which stores system-wide configuration settings. It provides direct read/write access to any registry hive on the local or a remote machine.
