The Windows registry subtree that contains information about the currently logged-on user is the HKEY_CURRENT_USER (HKCU) hive. This hive includes user-specific settings and configurations, such as preferences, environment variables, and application settings. It is dynamically linked to the HKEY_USERS subtree, which holds profiles for all users on the system, with HKCU representing the active user's profile.
