Types of Registry Keys

HKEY_CLASSES_ROOT  : – data on DLL files and applications is stored.

HKEY_CURRENT_USER  –  current user’s individual customizations are stored and tracked.

HKEY_LOCAL_MACHINE: – all of the software installed on the computer. Virtually anything that the operating system might need to know about a particular application is stored here.

HKEY_USERS: – all user data is stored. If multiple people use the same computer, all their user profiles are stored here. When a user logs on to the computer, the data is written to HKEY_CURRENT_USER.

HKEY_CURRENT_CONFIG –  This key points to the current computer hardware configuration in the collection of configurations stored in HKEY_LOCAL_MACHINE. This enables the use of multiple computer hardware profiles.
