Where Is The Windows System Registry Hive?
Registry Hives - HKCR, HKCU, HKLM, HKU, HKCC, and HKPD
This section provides quick introductions on the Windows registry hives - top level registry keys on Windows XP systems.
Data stored in the Registry is divided into several predefined sections called "hives". A registry hive is a top level registry key predefined by the Windows system to store registry keys for specific objectives.
On my Windows XP organisation, the Registry has 6 registry hives:
- HKCR - Abbreviated from the registry key name HKEY_CLASSES_ROOT. HKCR stores information nigh registered applications, such as Associations from File Extensions and OLE Object Grade IDs tying them to the applications used to handle these items.
- HKCU - Abbreviated from the registry key name HKEY_CURRENT_USER. HKCU stores settings that are specific to the currently logged-in user. The HKCU key is a link to the subkey of HKEY_USERS that corresponds to the user; the same information is reflected in both locations.
- HKLM - Abbreviated from the registry cardinal proper noun HKEY_LOCAL_MACHINE. HKLM stores settings that are general to all users on the figurer. On my XP organisation, HKLM contains five subkeys, HARDWARE, SAM, SECURITY, SOFTWARE and Arrangement.
- HKU - Abbreviated from the registry key name HKEY_USERS. HKU contains subkeys respective to the HKEY_CURRENT_USER keys for each user registered on the machine.
- HKCC - Abbreviated from the registry key name HKEY_CURRENT_CONFIG. HKCC contains data gathered at runtime; information stored in this cardinal is not permanently stored on the hd, merely rather regenerated at kick time.
- HKPD - Abbreviated from the registry key name HKEY_PERFORMANCE_DATA. HKPD provides runtime information into functioning data provided by either the operating system kernel itself or other programs that provide performance data. This key is not displayed in the Registry Editor, but it is visible through the registry functions in the Windows API.
If you lot run "regedit.exe" on a Windows XP system, you should see 5 visible registry hives as shown in this picture:
