Registry Supporting Files - Registry Backups

This section provides quick introductions on how Windows uses supporting files to backup registry keys and values.

Out of the 6 registry hives, 2 of them, HKCC and HKPD, gather information from the running operating system and applications. They do not need to store any information permanently on hard disk files.

But the other 4 registry hives, HKCR, HKCU, HKLM and HKU, do store information in supporting files that contain backups of registry keys and values.

HKCR - HKEY_CLASSES_ROOT: This hive does not need any supporting files, because it contains registry keys compiled from HKCU\Software\Classes and HKLM\Software\Classes.

HKCU - HKEY_CURRENT_USER: This hive does not need any supporting files, because it links the sub registry key under HKU (HKEY_USERS) for the current logged in user.

HKLM - HKEY_LOCAL_MACHINE: A set of supporting files are used for each sub registry key in this registry hive except the HARDWARE key which is created dynamically:

HKU - HKEY_USERS: Contains all the actively loaded user profiles on the computer with one sub registry key per user. A set of supporting files are used for each sub registry key:
