Which windows registry subtree get all it information from the hkey local machine subtree?

The Windows registry subtree that gets its information from the HKEY_LOCAL_MACHINE (HKLM) subtree is HKEY_USERS (HKU). Specifically, user-specific settings and profiles are stored under HKU, which can include information that is derived from or related to the machine-level configurations found in HKLM. This allows user profiles to access machine-wide settings and configurations as needed.
