Which registry key provides the Last Password Change for a Windows user?

The registry key that provides the Last Password Change for a Windows user is typically found under HKEY_LOCAL_MACHINE. Specifically, password-related information, including the last password change timestamp, is stored within the security hive of the system registry, specifically under the subkey related to user account information and security settings.

In Windows, HKEY_LOCAL_MACHINE contains configuration information for the machine, including the installed software, hardware information, and more importantly in this context, the security settings and user account information. The details regarding user accounts, such as password policies and last password change timestamps, are stored here, allowing administrators and forensic investigators to retrieve critical information about user accounts on the system.

The other registry keys have different purposes. HKEY_USERS pertains to user profiles on the system, while HKEY_CURRENT_USER focuses on the preferences and settings of the currently logged-in user. HKEY_CLASSES_ROOT deals with file associations and COM object registration, which are not directly related to user account security details.
