In the Windows Registry, which root key contains settings applied to all users on the computer?

Explanation:
The key that contains settings applied to every user on the computer is HKEY_LOCAL_MACHINE (HKLM). This hive stores machine-wide configuration that affects all users, such as installed software for the entire system, services, drivers, and security policies. In contrast, HKEY_CURRENT_USER (HKCU) holds settings specific to the user who is logged in, so those preferences don’t apply to all users. HKEY_CLASSES_ROOT (CLASSES_ROOT) is a merged view of file associations and COM class registrations, not a general all-users configuration. HKEY_CURRENT_CONFIG contains information about the currently active hardware profile, not general system-wide settings.
