Registry analysis
There is a great deal of activity that occurs under the hood of the Windows operating system. One place where this activity occurs and is documented is in the Windows Registry. The Windows Registry is a database that stores the low-level system settings for the Windows operating system. This includes settings for devices, security, services, and the storage of user account security settings in the Security Accounts Manager (SAM).
The registry is made up of two elements. The first is the key. The key is a container that holds the second element – the values. These values hold specific settings information. The highest-level key is called the root key and the Windows operating system has five root keys, all of which are stored on the disk in the registry hives. These registry hives are located in the %SystemRoot%\system32\config
folder on the Windows file structure:
HKEY_CURRENT_USER
HKEY_USERS
HKEY_CLASSES_ROOT
HKEY_LOCAL_MACHINE
HKEY_CURRENT_CONFIG...
